My 9 month old acts like he's getting back teeth in. He seems like he's getting more teeth& always put his fingers back far and chews on them. I've looked at his gums and doesn't look like any new ones coming in. Right now he has his bottom middle 2 and his top eye teeth I guess, the pointy ones lol. Could he be getting back teeth?
