So I'm not sure, but I think Xander might be constipated. He hasn't pooped in 4 days and sometimes will randomly cry and I'm not sure why (he also could be teething). Lately, for solids he's eaten cereal, carrots, and apples, all of which I think can cause constipation. I wasn't sure if I should hold off feeding him anymore constipating solids until he's had a bowel movement? Or are there any other suggestions?
