What baby poop says about your baby's gut health.
Time to check that diaper.

The Evivo Scoop on Baby Poop

If your newborn infant is fed breast milk, you might be told to expect him to have five to eight poopy diapers per day, with each baby poop appearing loose or watery. Why loose or watery baby poop? Why five to eight poops a day—is that really normal? What’s normal for baby poop anyway?

First, it’s important to know that breast milk’s third most abundant nutrient isn’t food for the baby - It’s food for baby’s gut bacteria and supports his developing metabolism and immune system.

Baby poop is a visible signal of ‘good’ versus ‘bad’ bacteria in baby’s gut. The more ‘bad’ bacteria that are present, the more a baby will poop since the gut is not able to absorb all the nutrients from breast milk – babies just poop them out. The more ‘good’ bacteria, the fewer poops since the baby is able to absorb all the nutrients from breast milk.

Evivo Colic Testimonial

Do your baby a solid.

Feed Evivo to your baby every day and you might just see a difference. In our clinical studies, the babies taking Evivo had, on average, just two to three soft, well-formed baby poops each day. Some had fewer, pooping only every few days. Just two to three, instead of the somewhat continuous five to eight watery ones. That’s the activated probiotic at work.

Well-formed – the result of being well informed. That sounds better already.

    Not a Dairy Allergy
    My daughter was having 7-10 mucous poop diapers a day, and eventually had blood in there too. I was convinced she had developed a dairy allergy. This was my last shot before changing my diet and placing her on alimentum. After 2-3 days she reduced to 2-3 poop diapers a day and mucous/blood was gone! Would definitely recommend trying prior to changing diet/formula! Oh and she was a c-section baby too!

    We love Evivo
    We are so happy with how Evivo has worked out. No more diaper rash and only a poop every other day. I'm confident that my sons gut bacteria is being restored to lead to a healthy life!

    So far so good!
    Our little guy has been on Evivo for about a month. He’s not near as gassy and does not poop as frequently which ultimately allow his diaper rash to clear up. We are still on reflux meds. It I hope in time we will be able to take him off those as well. We have already cut back from twice a day to once a day. I call that a win!

    Life changing for baby!
    After I had taken an antibiotic for Mastitis, my son was no longer the easy going baby he was for the first month. He was now constantly fussy, gassy and no longer sleeping well. He stopped having full bowel movements, instead he would just have a little smear in his diaper EVERY single time I changed his diaper which was giving him a bad diaper rash. The antibiotics had messed with his gut health. After just one day of being on Evivo his gas improved and he had the biggest poop of his life. You could tell he was feeling so much better. He is back to being our happy go lucky baby!

    Worth the money
    My newborn son was having terrible gas pains after breastfeeding and would poop 8+ times a day which led to a horrible diaper rash no matter how clean and dry we kept his bottom! After a few days on evivo, my son was pooping 1-2 times a day and the diaper rash disappeared! He is also sleeping better now that he doesn’t have such bad gas pains. Can’t recommend this product enough!

    My newborn was crying and struggling with gas and stomach pain in the days following birth. Gas drops helped temporarily, but after some research I identified that the antibiotics I had been on during labor may have disturbed his gut flora. After several days on Evivo, he went from several painful poops per day to having a dirty diaper every few days with much less visible discomfort!

    Very helpful
    Evivo has really helped with my son's reflux and diaper rash. Before starting Evivo, and even when we miss a few days, he spits up more and has more runny poop causing diaper rash.

    Our daughter had colic and was pooping 8-12 Times a day with every diaper. Within 24 hours of starting evivo, her colic stopped and she only poops 1-2 Times a day now! Love it!

    Game changer!
    We are so thrilled our friends recommended evivo after we had told them about our baby being fussy and cranky with stomach cramps at night. After only two days of evivo we went from having poop in the diaper every time we changed her to having one big poop a day and no more stomach cramps and fussiness! We recommend evivo to all our friends with little ones!

    Sleeping better and no more diaper rash
    We decided to try Evivo after my son was having a lot of gas pain. He was waking up frequently and having frequent, small poops every day that was causing him to have a diaper rash. I did a lot of research and chose Evivo because it has been clinically tested and that was important to me. I had to have IV antibiotics when I delivered him and a few weeks after due to mastitis. I read that those can kill the babies good bacteria so we thought we’d give this a shot. I’m sure glad we did! It took about a week to really see the improvement but it was so worth it.

    I love this product!
    My daughter was a c-section baby with antibiotics given to me at birth. Then she was hospitalized at 2-weeks-old on IV antibiotics for two days. She’s exclusively breastfed but once we got home from the hospital her poop started to smell AWFUL and she was very gassy. I had to spend a lot of money on Windi and she cried a lot due to tummy pain. I researched probiotics and decided to go with this one to help get her back to her natural microbiome. She didn’t like the taste at all and gagged giving it to her right from the syringe. I started giving it to her while actively breastfeeding by tucking it under her lip and pushing slowly. She doesn’t even notice now and actually seems to enjoy the faster flow of milk with the syringe. There’s no gagging or bad side effects. It smells like wet puppy food to me when you mix it. Within a week her diapers smelled back to normal and now she goes poop once or twice a day or sometimes every other day. Her poops aren’t painful and she seems like a happier baby. I don’t think it’s any coincidence her poop smelled so bad for 3 weeks after the antibiotics and it cleared up so fast with Evivo! I will keep her on this for several months.

    The Rash is Gone
    My second child had the same angry butt rash as my first so I just thought that it was normal but after reading about the imbalanced pH causing the rash, I decided to order Evivo. I wasn’t sure it was necessary because I had had a natural birth VBAC but the lactation consultant suggested it was worth a try. Within 2 days my daughter’s butt rash was clear. It has helped regulate her digestive system so she poops only 1-3 times a day instead of every diaper change. We don’t have to call her “super pooper” like we did for my son.

    I loved using Evivo....my breast milk supply is almost gone so I’m not sure I can continue using, unless I mix with formula? But if I were to still have Breast milk I would continue giving to my daughter. Within 2 days we saw her bowel movements become so regular, she is continually having dirty diapers instead of not pooping for 2-2.5 days. Her gas and reflux cleared up, she burps way easier! Overall I really do think Evivo helped with my daughters tummy problems! I may continue giving to her even with formula, I figure it has to still do something with the formula as well!

    Would recommend to everyone!
    My daughter started having all the signs of tummy trouble at about 2 weeks old. She was fussy and gassy at night, woke up a lot, and was having a poop with every diaper change. We started Evivo and within 5 days ALL of her symptoms had greatly decreased. She now poops 1 time every other day and the evening fussiness doesn't happen nearly as often!

    Effective after first week
    It’s my first time to have a colicky baby as in 7 hours of nonstop crying. He is still fussy but I have noticed a huge improvement. The smelly poop comment I have read on reviews, I didn’t experience that with my baby. I think his poop still smells the same. The most noticeable improvement that amazes me is that he never had diaper rash again.

    Evivo helped us so much!
    Our baby was so gassy and fussy from the beginning, and he had 6-8 really runny poops a day. After starting Evivo (within 24 hours), he has only had 1-2 dirty diapers per day or every other day, and they look so much healthier! His gassines is much more manageable, and we can definitely tell a difference if we happen to miss a dose.

    fewer poops!
    Not sure if there's been much a difference in his temperament (we've only be using evivo a week), but he has fewer poops. We used to have to change him after every feed, but now his dirty diaper are only once every day or two (though they are extreme when the happen).

    Working for us!
    Honestly our baby’s biggest issue was pooping all the time! And it was super watery so blow outs were frequent. It’s so different now. And she may only have two dirty diapers a day! No more red bottom!

    Actually works!
    We’ve given our 4-month old Evivo for several weeks now and we’ve noticed that his gas has reduced, his poops are more regular and less frequent, and he doesn’t have a little poop in each diaper making diaper changes so much quicker! You can tell it’s working! We did not have these effects with other infant probiotics. Thank you Evivo!

    Love it!
    My son was pooping a very small amount with every diaper change which led to some serious diaper rash. Immediately after starting Evivo, he stopped pooping as frequently and now can go days without any discomfort. He also passes gas with less pain now. I’m so happy we found this product, and I only wish it had been around when my first son was breastfeeding. We’ll definitely continue using this for as long as my son breastfeeds.

    Great so far
    My baby’s poop has regulated. She also has not had a diaper rash since we started using the probiotics!

    Happy Baby, less frequently diaper changes
    Really easy to use - we made it part of our bath routine. After a few weeks, she started having more regular poops...none at night and a big one early in the morning. Not having to change a diaper in the middle of the night is a big win for us! She also seems less gassy. Still needs to be burped, but it’s been awhile since she’s had painful gas in her tummy. I just wish powder would dissolve better... the graininess took awhile for baby to get used to.

    Smelly but works!
    I am impressed with how quickly we saw a difference in our baby boy after starting Evivo. He was having painful gas and many small poops throughout the day, but now he passes gas more easily and has a "mega diaper" every couple days. As far as the smell, it's a little strong, but my guy tolerates it fine. I wish it dissolved more thoroughly, but I have been having luck feeding the excess to my son directly followed by the syringe.

    More regular poops :)
    We are a month in and my daughter used to poop in every single diaper. Now most of her diapers are poop-free and she has 1-2 big bowel movements every day or so. It seems to be leveling out her system! She still does have some gas issues that wake her up, but they are less severe and less frequent since using Evivio.

    Helped our baby!
    Our breastfed baby started having tummy troubles around 5 weeks old. He had frequent and hard to pass gas, very watery/explosive green poops, and trouble sleeping due to the discomfort. After trying gas drops, gripe water, reflux meds, and different breastfeeding techniques/solutions, our doctor suggested we try him on a gentle formula. I was not ready to give up on breastfeeding yet, but also didn't want to put my little guy through any more discomfort and sleepless nights. We tried Evivo as a last resort; it made sense to me to try to fix the cause of the problem rather than treat the symptoms. It wasn't until recently that I realized his issues started when I was prescribed a course of antibiotics otherwise I may have tired this sooner! Within a week, his poop was back to yellow and within two weeks, the consistency was back to normal (no more water sloshing around in the diaper!). Added bonus-the bumps all over his chest and legs were also gone. At 3 weeks now, his gas has improved but is still the main issue he's having. We're hoping it continues to get better and will continue using the product.

    Great service and so far good for Baby
    Evivo came quickly and was packaged perfectly. It’s easy to use and so far my baby has responded well. Right after starting Evivo, she regulated from poops every diaper change to 1 a day! I also think it has helped her stay healthy and not get any colds!

    No more diarrhea!
    My baby was having green, watery diarrhea with every feeding and had horrendous diaper rash that wouldn’t go away. She would sometimes poop 8 times a day. I started her on Evivo at 5 weeks old and noticed a difference within days. She has now been on it for 3 weeks and is only having 1-2 poopy diapers a day! And her poop is now yellow, seedy and much more solid. Her diaper rash is completely gone and she is such a happy girl! She only gagged and spit up one of the first times I gave it to her, and it was because she had a very full tummy. I am always sure to give it to her before I feed her and squirt small amounts in the side of her mouth. She takes it like a champ!

    Baby immediately more regular
    Within the first week our four month old went from pooping once every 7-10 days to once every 1-2. He seems happier and we those diaper changes aren't such an ordeal any more. We will continue to use it!

    Thank you Evivo!
    I discovered Evivo as a client relationship, and quickly discovered our newborn had experienced a lot of the things (c-section birth, wife was on antibiotics during labor, and he was on formula the first 4-5 days after birth) that lead to not having the right bacteria. He was extremely fussy after bringing home, very gassy and had frequent, wet bowel movements that lead to severe diaper rash. We looked into anti-gas droplets and the probiotic product from Gerber; and both had minimal to no impact. After reading more about Evivo and speaking with their Lead Scientist and Director of Clinical - I decided to order a month trial kit. After 4-5 days, we saw clear results as he had less frequent, more solid bowel movements and was much less gassy. After a couple weeks - we further observed significantly reduced acne and more regular, less frequent movements. My wife was so pleased/relieved and we plan to continue using Evivo as our son continues to grow. While she was skeptical at first, she now views Evivo as a true life-saver. While we still have challenges with his sleep cycles, this seems more behavioral and hunger related, with the constant aggravation, gassiness, pooping and discomfort all but gone. We also noticed recently his belly is much less swollen - signs of improved digestion. Now I'm sure some of the improvements are attributable to natural growth and development, we feel Evivo was key in steadying the development and growth the right way - stomach wise. Thank you Evolve Biosystems, and keep up the good research!
