My baby is 43 days old he used to sleep day time and wake up only to feed but from 2 days he is being up entire day for longer hours like 4+ hours is this normal i try to make him fall asleep but he wont his eyes are wide open

A. dear mum , such phases are common as the day n night concept is not formed also there are no strict sleep cycle baby may stay awake more feed especially when experience growth spurt if otherwise active alert gain adequate wt dont worry
