It can be teething.. My daughter has been teething since about 2 months... None of her teeth have broke through but I can see the white spots. Also she probably just discovered them. My daughter sucks on her hands all the time

My son does the same thing he usually tries to chew them when he is hungry lol so with that & him giving his little tiny attitude thats how we know he is ready to eat

My daughter does the same thing

@karnawest, @mrs.cravens yea that's true. Just new to me lol. Although it is cute 😂😍

She just discovered them. Could be trying to use them like a pacifier. Little early for teething but I would say that's next

babies put everything in there mouths lol
