Our dr said that's a normal developmental skill at that age but can be a sign of the beginning of teething. Mine is 11 weeks and has been doing that and drooling since 8ish weeks and now you can feel 2 teeth but they haven't broke through yet

my girl started that about the same time to unfortunately no teeth yet.

I'm not saying your baby ISN'T teething, I'm daying you and the doctor while DEFINITELY know when it happens, it's obvious when those teeth are coming in. It isn't very common for a baby 3 months or younger to cut teeth, and sticking their hands in their mouth and drooling is a developmental thing that all babies do, even when not teething. We thought our girl was teething at 3 months because of these exact reasons, well she didn't get her first tooth until 8 months of age! And got her second tooth about a week later! So just saying, if you won't see or feel teeth right now, it's likely not teething yet it's most likely just normal baby behavior.

@hellosweetie, well she has been drooling a lot too.

they can start cutting teeth super early like that then the teeth pop out usually 1 to 2 at a time

My son had 2 teeth by the time he was 4 months old. It's possible.

It's a developmental thing, trust me you'll KNOW when they start teething, the drool is INSANE and you will see/feel the teeth coming up! They will look white and sometimes kinda dark because of blood vessels
