My eldest was 10mths when he got his first tooth - just in time for Christmas LOL. I wouldn't say that it makes it easier for them to get them later - he still did a fair amount of crying from them and he was off his food for a week or so and got lovely teething poos. Oddly though each one has gotten them a little earlier than the previous one - my 2nd got her first at 9mths, my 3rd got them at nearly 8mths and my fourth has more teeth at nearly 9mths than the others did at 12mths LMAO.

Don't know about the correlation between us getting them and when our kids do - I was born with two teeth and Dh got them at the *average* time. The only thing I have noticed though was that my eldest started losing his baby teeth later than his classmates - so maybe the later they get them the longer they have baby teeth for?
