My baby is 3 month and 20 days old and having dry diaper for 6 to 8 hours during night and poop once in a week. Is it normal

A. dear mother if a diaper is a dry throughout the night then there is nothing to get worried it is good in fact that your child is able to sleep properly at night make sure that if you are a feeding mother you must eat healthy and stay hydrated at regular intervals are but passing a motion once a week is not a good sign it is the sign of dehydration you must apply mustard oil on babies potty area and massage is dummy with him water or warm oil rotating and clockwise and anticlockwise putting pressure gently and once concerned with the doctor
