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.

    Life changing!
    My 4 week old was getting very colicky. He would cry for hours, had lots of tummy discomfort like gas and trouble pooping. Every diaper change was a little bit of poop but not much, which lead to terrible diaper rash and prescription medication. He was miserable. We tried a probiotic drop but it didn’t do anything. Finally after leaving my sister’s baby shower in tears of frustration and discouragement because I couldn’t help my son enough to ease his discomfort and crying I ordered Evivo. After the first day I noticed his gas smelled stinkier. Something was definitely happening in his gut from day one! After 3-4 days he was a new baby. He was calm relaxed and happy. His poops turned into one or two big ones a day and he hasn’t had diaper rash since. He only cries now if he’s hungry, wet or is tired of daddy and just wants mommy. Haha. I am complemented every single day on how happy and chill my baby is. I tell everyone it’s Evivo. He’s such a sweet little guy and I’m so thankful he’s not in pain anymore. This stuff is a miracle!

    Helped us!
    Our baby had lots of gas and was also pooping every single diaper which resulted in diaper rash. Now he poops once every 1-2 days and his gas has gotten much better! No more stomach pains and cries. Thanks Evivo!

    No more diaper rash!
    I was on antibiotics during labor, and our LO would have little watery diarrhea-like poop squirts in his diaper every change which resulted in horrible diaper rash. After giving him Evivo, no more diaper rash and his poops are now regular!

    Regular BMs have made my baby comfortable
    I have a healthy, almost 7 week old, baby. Before Evivo my little man use to poop multiple times a day and shart (sh*t-fart) every single diaper. He would struggle all the time to fart and poop. He would always be hungry and My milk supply couldn't keep up and I would need to supplement with formula.. Now we have been using Evivo for almost a month and he poops every other day. He gained over 4.5 lbs since he was born. To me it seems that the good bacteria helps him "absorb" more nutrients from my milk. I would have given this 5 stars but the first time I gave him this treatment I did it right before bedtime and he kept me up all night. It was a rough in our household for a few days while his stomach adjusted to the good bacteria & got rid of the bad bacteria. It would have been nice to have known this before starting this. I do recommend this product and will continue this treatment for as long as I can afford it for the 1st 6 months of his life.

    Best $100 ever spent
    Our baby was having a difficult time with very watery poops that weren’t the usual BF baby consistency and causing intense diaper rashes/skin breakdown that was hard to keep under control and seemed to cause our one month old pain. No change in my diet or BF patterns seemed to help. Her pediatrician recommended Evivo and I’m just a few days we noticed a difference!

    No more watery diapers and diaper rash!
    My son was flying through diapers in his first month of life as he pooped pretty much anytime he had gas (so constantly) and developed a diaper rash that led us to change him frequently. We are down to just 5 or 6 total diapers a day, which is normal for his age (2 months now!) It's so much less work than constantly changing poopy diapers, the consistency of which is now normal, and obviously led to the disappearance of his diaper rash. Thanks for saving us on diapers and wipes and helping our son achieve greater gut health!

    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.

    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!
