when does baby start growing teeth
Babies may begin teething as early as 3 months old, or well after their first birthday, but 6 months of age is a fairly common time for teething to begin. Your child's behavior may clue you in to when it's almost time for a tooth to emerge, or erupt, through the gums. Babies are often fussy for up to five days or so before a tooth breaks through. Their gums become tender, sore and swollen.
