My DD(8) got her first tooth at 14 months. Seriously, I was just about to organise dentures. She did teethe quickly and had all her deciduous teeth, including 2 year old molars, by 18 months. She was already so settled in her sleeping routine that teething was no problem at all - she would wake up in the morning and I would realise she had sprouted a new tooth! She 'cross cut' so new teeth just popped up all over the place in no particular order.

She also seems a little slower to lose her deciduous teeth than a lot of her peers. She had 6 adult teeth now but no loosies happening.
