My DD1 didn't sleep through until she stopped teething which was after 2 years of age. We also had her give up her dummy to the dummy fairy and so she doesn't wake for that anymore either. She wakes every so often but more like once every two weeks, and usually because she's had a bad dream. It does get better. I have to keep telling myself that, as my 15 month DD2 is waking often at the moment. Big hugs xx
