Not according to an article I just read...or my personal experience. It said that baby's BM routines will change quite a bit after starting solids, sometimes skipping a day or two. Every time my dd skipped a day, my dh would assume she was constipated every time she'd cry and he hasn't really been right yet. :wink: I wouldn't worry for another day or two. However, depending on what you've introduced so far, you could offer more of the "stool loosening foods" versus the "stop-em-up foods" just to make sure things keep moving. Unless of course you're only on cereal and then I'd just make sure they're getting enough liquids as well. HTH
