I have a 2y10month gap between my two. We started trying when DD was 6months old too as we only wanted an 18month gap.

I agree with a PP who said you deal with what you get.
I love that age gap and we will have a similar or greater gap if we decide to have another. My DD still had day sleeps until 3.5 so I could still catch a rest, and having her TTed and in a bed way before he was born was fantastic.
