2weeks and 5days old feeding /sleep

Li

I currently wake up my baby during the day so she eats every 3 hours. She has passed her birth weight by a good pound and a half. She isn’t a good night sleeper maybe sleeps 5 hours and that’s broken, My question is should i be waking her during the day to eat? I breastfed and once a day I’ll pump a 3-4 oz bottle which she’ll drink. i feel like she may not be sleeping enough
