Is she getting enough?

Tiffany

So baby was discharged from NICU today and we're home. Ive been trying breastfeeding and at first she only took a little and didn't seem interested. Today I tried again, and she latched with the nipple shield and did pretty well, I wanna say maybe 5-10 minutes? She ended up knocking out. Like k.o lol. I pump and have a ton of milk stored up, and she was taking 2 oz from the bottle so now that I just breast fed and she's out, how do I know if she's getting enough? Should I feed her the bottle just in case? Any tips? Thank you!
