My 5 months old baby boy is keeping is lower jaw like it shown in the picture frequently. stretching and keeping it cross sometimes for few seconds and keeping normal again. is this normal or should I see a doctor?

A. Look it seems like your child is not not having any kind of discomfort while doing it so some kids generally do it it’s not an issue also when teeth start to come discomfort in the gums also such a situation can be seen but if you want you can check with your doctor for better clarity
