Born 36w4d

My baby boy was born on Tuesday 9/28 at 36w4d and he weighed 6lbs.

I would love some tips and advice on caring for a late preterm baby. My first was born at 40 weeks on his due date and I can already tell the preemie sleeps a lot more.

I am breast feeding and pumping but idk if I'm doing it right 😕 when I breast feed he will do 10-20 mins on each side but he will be hungry not even an hour later, when I pump he drinks 1oz and won't be hungry for another 2-3 hrs. The bottle feels wrong bc he drinks it in less than 2 mins so I'm like is he actually full? Am I tripping lol

I want to add that I'm new at breastfeeding, my first son was tongue tied so he never properly latched and I didn't produced enough.
