Hello, my baby's is 2-3months old, these days she jerk while little bit loud voice and sounds in sleep also, but suddenly now she is not jerking for any sounds and she is sleeping well with that sounds also is it normal or not?

A. Hi mom jerking in the initial months after birth is due to underdeveloped muscles which is normal.. Secondly sound while breathing is also normal as this is grunting voice which will be fine on its own provided the baby is not having cold cough
