My two months old boy cries before he passes soft stool, from yesterday. i thought he was constipated but he was not, this happens after feed.. ?

How fed ????: A breast fed infant may stool a bit every feeding or an overflow diaper once a week. If it is soft it is not constipation. If formula fed, the pattern is more likely to be a few daily or at least every other day. If stools are soft & baby feeds well & plays, there is no reason to be concerned. Babies can cry to push stool with their breathing muscle since their belly muscles are weak
