Evie has just had her first two teeth out and two more next week. She has to have retainers. I spoke to the dentist as I know from my Melissa test that I have a problem with Nickel and explained my worries. They wern't at all helpful,, in fact thought I was slighlty weird. She is going ahead as she o r Keith think I'm worrying too much. What can you do but advise. Love Tracy xxxx
