my DS2 is younger then your DD and im pretty sure my DS2 is teething already like moving around in his gums and so fourth my Dr even said it is possible that he could be getting pain from it now also

My DS2 hates dummies but stick one in the freezer get it nice and cold and he goes hell for leather on it, he chews my finger/nipple especially my nipple all the time and his gums are mighty white!

Goodluck i hope she settles down with it eventually
