I actually had the opposite experience with my son. When he was a newborn and wasn’t eating solid food yet he didn’t have any solid poos and was blowing out the Pampers at least once a day.

Once he was size 2 we started buying store brand but it was also the same time he started eating real food so he would blow out far less often. Now he’s 11 months old and hasn’t had a blowout in probably a couple months and we’ve been using store brand diapers with great success
