My baby is 1 month 7 days old and by today 5 am he is not sleeping at all is there any pblm in it

A. just a day ir two is no issues. sometimes due to weather or any discomfort its normal. It's quite normal in newborns .That's how they function. It's not a concern. After few months they will start to follow a sleep routine. Follow a sleep pattern ensure to put your baby to sleep at the same time every day. Feed a little more during night hours for good sleep.
