This is very interesting, it`s something I`ve never thought about, I guess mainly because I didn`t meet my DH until I was 28.5 years of age.

My first (Matthew) was born 2 months short of my 31st Birthday.
#2 is due 26 days after my 32nd Birthday.

I`m wanting 4 children and at this stage I`m thinking of trying for #3 when #2 is 1 year then have #4 as soon as possible after #3 but this will all depend on personality of #3, if it`s a dufficult child I might wait longer if it`s a easy going baby like Matthew it might be sooner that I try for #4.

So that will make me a minimun of 35 years
