LO (17 months) was prescribed amoxicillin for the first time this week. I was told one of the more common side effects is that it causes diarrhea, because it also clears out the good gut bacteria, and to try probiotics to help.... I'm just curious, when your LO was on antibiotics, did he/she get diarrhea? How bad was it (i.e., more times than the normal number of poops a day?), and how old was your LO? Also, did it take a while to resolve once the antibiotics were done?
