I really like that it immediately helped the poopsplosion issue my 4 month old was having. It is also great that it doesn't need to be refrigerated. Baby was ok to accept all 5 drops most days, it wasn't too difficult to give to her when timed right.
The downside is that the tube only lasted just under 3 weeks, I guess they are trying to match the price point of other baby probiotics. Also there is only one probiotic strand, so while it helped reduce poop leakage it didn't eliminate the problem entirely. Still, it is much easier to deal with then the powder one I have. I rarely use it because I am currently breastfeeding exclusively.
I bought this because I couldn't find the GNF colic drops. I may buy it again, but I'm looking for the GNF drops before I do.
