Dear parents, Passing stool with every feed in newborn is a normal phenomenon what we called gastrocolic reflex. My concern is rash between the buttock. It may be due to fore milk diarrhea or delay in cleaning the buttock area. Apply zinc oxide cream, clean the buttock immediately when baby passes poo and allow air day. Advise to give one breast full feeding and then switch to other breast.

It's normal if it's breast feed and may be it's diaper rash and u can use rash free cream.
