My baby of 10 months and 3weeks has only 2 teeths is it normal?
Yes it is very normal, babies attain their developmental milestones differently. At 10months, some babies would have no tooth, some would have 2, I know a baby that had 8 teeth by 10 months.
Babies start cutting their first set of teeth averagely around age 5 - 7 months. However some babies can be earlier and some are even born with teeth
and rounds up at age 3 with the first set of teeth(milk teeth) which are 20 in number. You only have to worry if your child has not attained this at 3 years.
