Kirsty.... They can pop up & down & come & go for quite a long time a few months....

I hope it pops through soon, there are special dummies that I have seen in Chemists that are a dummy but the shape of like a mouthguard & all rubbery & rough with nobbles (?)... They can chew on & it will relieve the pain but might also help the tooth cut through???

Sorry I cant think of the brand.... It might be happy baby (with duck on it)
I had planned on getting one when Indah was teething but all of a sudden she had her teeth & sharp little things they are, we also give her teething rings from freezer, another tip is a damp gace washer in the freezer for a little while for her to chew on.....

Good Luck...
