A. Hello dear parent! It is a normal finding in small babies to keep fingers and things in the mouth, it is a way of exploring things and body parts. Keep cleaning your baby’s mouth and hands frequently. Maintain a good personal and oral hygiene for your baby. Watch out if your baby is teething. Continue breastfeeding.
