Whoooops I just noticed you said 6 WEEKS ...yeah at 6 weeks he should eat every 2 hours. 2-3oz every 2 hours what I said earlier was for a 6 month old

My 6 week old baby girl has 4oz very 3-4 hours but every baby is different like my son he took 6oz every 4 hours an my oldest daughter she took 2oz every 2 hours from the time she was born to the time she stopped drinking a bottle so baby's are all different

At 6 weeks my kids all ate every 2-3 hours I think at that age 4-5 hours is too long of a gap

Baby will tell you if he’s had enough but my 2 were eating 6-8 oz every 4 hours. Does he seem content with that amount and did you guys introduce solids yet?
