About a month ago, D got bronchitis and was started on antibiotics. Antibiotics always mess with his gut, so I started giving him Culturelle probiotics (the chewables) at the same time. While he was on the abx, he got probiotics 2x a day, but we dropped to 1x a day when the abx stopped. He was off them for a couple of days for his surgery, but started right back on them 2 days after surgery. Well, since surgery (which was 3.5 weeks ago), he's been having issues with constipation - to the point where the other night he was crying in the tub that his bottom hurt then woke up the next morning with a MASSIVE hard poop in his diaper. He's cried a few other times that his belly hurts, and then hours later has tiny little hard rabbit turds in his diaper.

I know that anesthesia can cause constipation, so for the first week or so I chalked up to that, but that can't still be affecting him now. His diet is pretty much the same as before surgery. The only other difference is he's on 1/2 baby aspirin a day.

Has anyone else's kiddo ever had the opposite effect from probiotics?
