What's the record for the most bowel movements in a 24 hour period? My one-year old had five in one hour last night. Not little ones but diaper bursters. His pace has slowed since than but I still had to take out the garbage about 4,000 times today. I think it's because he finished his anti-biotics and the natural digestive system bacteria are reviving. If he wasn't otherwise so healthy now, I'd be worried.
