15 month old has dummy for sleep, and sometimes during day. Spoke to my dentist about the fact she has a big overbite, and he said probably best to stop dummy now. We took dd1's dummy away at 6 months, and although she screamed a bit it wasn't too bad. I have a feeling it will be hell with dd2, as she seems to love her dummy. Any hints on how to do it without traumatising her (or us) too much!
