babies and teeth

Bethany

my 1 year old son had 8 teeth that I knew about up until yesterday. I was feeling around in his mouth cuz he put something in his mouth that he shouldn't have and while I was in there I discovered he has all 4 sets of molars as well. theyve all popped through. Has anyone else's babies went through this at an early age? should I be worried?

picture for attention.
