For my DS first 24 HRs he did not seem to be very hungry, he was still good on supply from the belly i guess, then he did start eating every 2 hours, is very normal the first days and it will settle when milk supply comes in and gets going. What i did was talk to him a lot during the day and made noght feeding a litlte more boring so he would see a diference between day and night. To get her going stoke her cheak and her jaw, then they remember what their supose to do, remember this is a huge task for baby to accomplish,
hang in there and best of luck
