Feeding

Leah
Hey mamas! I had a quick question . My baby was a preemie born about 3 and half weeks early . She didn't spend anytime in the NICU and we got to go home  after 2 days . She's very healthy . She's sleeps  more than anything so she has trouble latching so I pump every 2 hours and feed her that . My question is , is it ok for her to go 3 hours at night? And also how much do your babies drink ?
