My son is about 12 weeks old and for the past week he’s been constantly drooling bubbles, chewing on his hands and has been EXTRA fussy. My aunt said he could be teething already, this early? So I want to buy him those teething rings/toys that you can freeze I heard they help a lot but would it be bad for him since with the weather it’s been really cold. Have him to be chewing on something frozen? Or is it okay? Or what helped with your babies when teething?
