My eldest DD didn't get her first 2 until 9 and a half months. DD2 got 5 in 2 weeks at 8 and half months. A friend at playgroup has a daughter who is a bit over 11 months and still hasn't any. I wouldn't worry - all babies are different and develop at different times. I was told that it was better to teeth later if that helps? I don't know if it's true but I went with it, lol!
