when my baby was supplementing with formula but still mostly breast milk his dr said it's normal to go up to a week without pooping.but once it hits that 7th day they need to be seen.they tell u to lightly push on their belly nd to do bicycle motions with their legs and lastly put vasoline on a qtip nd just barley put It in their butt lol

@rellabella,

No just formula really

Is he purely breastfed?
