FTM breastfeeding help

Talia • Pregnant with baby #2!
I had my girl on thanksgiving at 10:16pm
I came home from the hospital last night and never got the chance to talk with a lactation consultant. My baby and I are getting frustrated trying to get her to eat. As soon as she gets my nipple in her mouth she just falls asleep... I know this is new to the both of us and its going to take time. I just need some advice! I want to make sure she is eating properly and getting enough nutrients
