Hi experts...I have a one month and 12 days old baby. he is on breastfeed as well as formula due to low lactation. when I breastfeed him I m not sure if he is getting enough milk and not hungry anymore. how do I know he is full or satisfied. is it possible that a baby is hungry but still go to sleep. he has colic and reflax issue. I am scared that keeping him hungry might increase the problem. can some please advise.
