Hi ladies! I had my baby boy on 8/28! I'm excited to join you ladies!

And I already have questions!

I am exclusively pumping. Baby is 11 days old and is eating 2.5 ounces every 3 hours during the day, but will go 5 hours through the night. I have to wake him for almost every feeding during the day. He is eating just over 17oz per day. Is this enough? Should I be waking him every 3 through the night? Please help!

TIA!!
