My DD is exactly the same, this time is worse cause I think there are 4 trying to get through at once. Bonjela kind of works, but I will have to try the SM-33. As for applying it, my DD doesn't have a dummy and I noticed when I put one in her mouth to try and get her to sleep cause I was at my wits end, she chewed it. Now I put the Bonjela on the dummy and she puts it in, and normally straight to the sore spot.
