My son has grown all of his in fours! Front four, four molars, and now four incisors. It is a miserably slow process for everyone involved, since he is a crabby patty a lot of the time. For him, the orajel (adult strength) does the trick. He likes it so much that he tells me when he wants it and has been since he was about 14 months old. I leave it out on the dresser within sight but out of reach and he lets me know when he needs it. He never asks for it more than twice a day and it seemed to take the edge off so he can sleep properly. Good luck!
