Past two days was good as first time i was feeding my 44 days old baby mostly breast milk and one time formula, before that it was more formula milk then breast milk. And  He took 20 min to eat mostly.  sometimes one hour. Today i had cut in my nipple. Im wearing shield and feeding its painful stillm applying nip cream. But baby is awake from 8 am to 4 pm. Im Feeding him still he cries. When we put cradle get up immediately. Crying. So i gv formula milk too after one hour feed as he look not satisfied. Today every feed is going beyond one hour and immediately he gets up . What could be the reason??
