Gentle and effective
My son is currently 3.5 months old, and we’ve been using these drops since he was about one month old. Our pediatrician recommended BioGaia up until around 4 months, when babies’ digestion typically matures. While my son isn’t colicky, I’ve definitely noticed a positive difference in his digestion when we give this. He goes regularly every day, and it seems to help overall with gas, fussiness, and digestion. It’s reassuring knowing it can also help with colic and constipation if needed. The dosage is very easy—just 5 drops once daily. We add it directly to his formula bottle with no issues. The bottle itself is small, but it lasts about 25 days with daily use, which is reasonable. One thing to note is that the drops are oily, so if you wash bottles by hand, you’ll want to clean them well afterward. That said, our Baby Brezza bottle washing machine cleans everything perfectly with no residue. Overall, we’re very happy with this product and plan to continue using it as recommended. Would definitely recommend to other parents looking for a gentle, pediatrician-recommended probiotic for their baby.

Only heavily studied strain for improving constipation, not just gas
I looked up something specifically for getting baby poo to be hydrated and not dry and clumpy or wet diarrhea. Because he was on Mary Ruth baby probiotics and they didn't help with anything at all. There's two strains that help with what I needed for my 6 week old that is combo fed but mostly on Enfamil Gentlease Neuropro Optimum at this point- and those are BB-12 and DSM 17938 probiotics. I only found the specific DSM strain in BioGaia and the other strain in Culturelle baby probiotics. However I think DSM is the one with strongest evidence. So I paired the two. I gave him full doses of both on day 1 and he screamed his head off with gas from the bacteria colonizing in his gut. It was unfortunately the sacrifice I was willing to make to get his little gut healthier. Day 2 he was fussing after half dosing him with both, as I only full dosed to get things started. On day 2 his poop was not horrible dry paste anymore but it wasnt the best still. Day 3 poop changed to a better color and was more hydrated than day 2. No more shrieking from the probiotics. Day 4 his poop was soft serve and he barely had gas. He slept 4 hour stretches all night and didn't wake up in agony like he used to before the probiotics. He has been getting half doses since day 2 and his stomach is so much better. I'm pleased with this product. Also daytime is better too, he isn't wailing from stomach pain anymore. I kind of wish I had done this from when he was born, I probably would have saved both of us grief. Edit: he is 2 months old now with perfect yellow soft serve poop that's a bit seedy. He also has been fully formula fed for a while now, meaning the probiotics have his poop looking like BREASTMILK poop! That is amazing. 2 weeks worth of probiotics got his gut working great. He sleeps 5 hour stretches all night and doesn't wake up in terror with gas and his poop no longer looks like green dry paste. Once again I am giving him Culturelle AND this product at half doses everyday, not just biogaia. Edit 3: 3.5 months and his poop is still yellow and seedy. And it smells like yogurt- lol. So these probiotics are key to keeping his poop perfect. It's gross but his poop is perfectly moist- it isn't watery and it isn't dry and nearly a matte chalk texture. My initial issue was his body just didn't hydrate his poop enough so he was constipated and in horrific pain, and it was pretty much solved within a month of using these with Culturelle. It is pricey though... but worth it. Also after a month of using he stopped having gas pains and he farts pretty efficiently now 😂

Relives constipation!!!
My baby has been pooping max once per day, as infrequently as once every 3 days, for over a month now. Within 2 days of starting these drops, she now poops twice per day! Amazing results I honestly did not expect it to work that well. She had been taking wellements probiotics, which clearly did not work (I found them hard to shake too).

Lifesaver! Like magic for my colicky baby!
My 5 week old was colicky and crying basically whenever he was awake. He was also getting about 6 doses of gas drops per day just to be able to sleep. This stuff is literally magic! He’s a happy baby when he’s awake now and doesn’t need any gas drops! I could actually cry. I will recommend this product forever!

Seems to be Working!
I like this product as it’s not easy to get my picky 10 month old to take anything that isn’t breast milk. She absolutely hates anything sweet but 5 drops of this is easy to mix or give straight. After just 2 days I noticed her constipation start to resolve. My only dislike is the other ingredient is sunflower oil and we try to avoid seed oils at all cost but that being said I’m glad it actually seems to work.

Great with our reflux baby!
I cannot praise these enough!! These drops have helped with my baby so much! I did not start using them with the intentions of stopping his reflux medicine but we were able to! It also helped regulate his bowels better. We bought the ones with added vit D last time and unfortunately, they made all of those issues return. I will definitely be sticking with these!

Life changing! Especially after the dog ate them…
I rarely write reviews but I thought it would be a good time to do it because I love the product. My son just turned three months old this past week and has digestive problems since day one. We noticed right off the bat that he always struggled to go to the bathroom and was always gassy. Around 6 weeks we noticed mucus and blood in his stool. We went in for a checkup that day and they suggested that he had a Cows milk protein allergy. My two options were to change to a dairy, free diet or go on a special formula diet. I have really enjoyed breast-feeding so I took the option of going dairy free which seemed to help only minimally. Fast forward another eight weeks; He is still experiencing discomfort, gas and reflux. We were referred to a specialist where they just reiterated that it is a cow’s milk protein allergy. I was struggling as a first time mom not knowing how to make my baby feel better while also dealing with postpartum depression, so I finally took the advice of a mom in my mom’s group to start him on a probiotic. I didn’t think it was gonna make such a difference , but it really was night and day. He was on the probiotic drops for about two weeks when our dog got a hold of the drops while we were out of the house one day I thought OK let’s just let it go for now, but that was the week from hell. He was fussy, angry, and upset all the time fast forward to 3 days ago when I finally re-order the drops and he’s now been on them for 24 hours and I have seen an improvement in his attitude and his bowel movements. Thanks, Cooper 😒. I highly recommend these drops for any new parent dealing with a fussy, gassy colicky baby especially a baby with a cow’s milk protein allergy, obviously talk to your doctor to see if this is the right option for you, but it was for us, and I am so glad we purchased these drops. We will be re-ordering time, and time again.
