Would not recommend this probiotic to anyone! I gave a single dose to my daughter over two weeks ago and she has been so fussy ever since. I constantly hear and feel her poor little belly grumbling, which was never an issue before. I feel so sorry for her, and being that this probiotic apparently colonize is so well, I only pray that I haven’t messed up her poor gut biome forever. Her stool also turned to green and mucousy for a week after the single dose was given. Also a problem I have never had with her before. After doing more research, I question whether it is truly a good thing to have the singular strain dominate the micro biome of a baby. Diversity is key.
