Alright. Ftm here but I also have very young siblings growing up and I dont ever remembering this happening with them. Recently my son keeps blowing out his diaper. And I mean BLOWOUT, like up the back, the front, out both legs, just everywhere. And there was a puddle of poo in the diaper too. He has done this the past 4 times hes gone poo. He goes about every other day. I tried sizing up the diaper , and he still blows it out.

Hes 10.5 weeks old and eats 8 times a day. 4- 5oz bottles and 4 breastfed. 2 of his bottles are formula hes been having since he was born. 2 bottles are breastmilk. We havent really changed much besides feeding him a little more frequently at night to get in the 8th feeding because he started to sleep through the night. I have no idea what's causing this. Has anyone else had this problem with their babies?
