my 15 days old baby is crying every night at 4 o clock and neither sleep at night . how can we understand the problem whether it is a gas or she is hungry

A. Hello good afternoon !! Babies cry because of hunger,diaper discomfort ,gas and colic pain. Feed every two hours and burp well,check the diaper and change every 3-4 hours. If the baby cries continuously for more than 15-20 minutes by stretching the body ,rejecting feed, the body becomes red then it is colic pain. Colic drops and gentle tummy massage will help .
