What age could a baby start teething

My son started at 4 months.. He has teething rings!

Thanks

my daughter started at three months. the two bottom ones are all the way in now! she is five months:)

He is also very fussy I called his doctor but they told me he can't teeth already

@rileyandhuntersmommy, if hes drooling constantly and chewing on his hands/fingers then he's definitely teething.

Thanks my son is two months I think he is starting but not positive

at any age really. my son started teething at 3 months but didn't have anything pop through till 6 months. He is now 9 months and is trying to cut 4 more teeth.

some babies are actually born with teeth.
