Help!?!

Ciara
I had my daughter 9/1/15 & right away she latched on & did amazing. The next day it started to become painful. But I pushed through. We got home tonight & I breastfed her around 940pm? Then I ended up giving her a bottle of formula around maybe 11pm? Just to give my nipples a little break since they are so sore. Well she has yet to eat..I tried waking her up & getting her to latch & she won't. She just sleeps. What can I do? I also tried skin to skin already. Any advice at all..
