Breastfeeding, Jaundice, sleeping a lot? Help!!

Okay, so my one week old had to be woken up to feed. She last fed at 11pm and I had to wake her up around 5:30am to eat, otherwise I’m assuming she would’ve stayed in her dead sleep that she was in. The hospital told us not to let her sleep more than 8 hours in between a feeding that, that was bad. She has alittle jaundice, and that’s why I woke her up because I’m scared she needs to feed to circulate it out! She eats a lot, like earlier she ate around 4 oz! And is still breastfeeding. I pump my milk for her sometimes, and that’s how I knew 4 oz. any advice?
