Hi baby z almost 3 months old and she keeps her hand in mouth many SIL said shez that so..I think it's so early..wts d reason for dat??

Actually small babies have habit of putting hands in mouth,so u should cover his hands with mittens to avoid this.Yes it is too early to say that baby is on teething

Babies keep hands in mouth for few more months. Try to take out hand from mouth. It's a phase and they will stop later. Baby is too small so I don't think so she is teething.
