#asktheexperts Hello Doctor, my baby is 20 days old. These days, he constantly asks for breastfeed every 30 min to 1 hour in the night. While feeding, he doses off and then when we try to put him down, he starts crying. He will do this for 2-3 hours from 9pm till 2 am or 3am. Then he sleeps. However, last night he did not sleep till 4 am. Is it all normal? His sleep pattern constantly changes.
