I've always wanted more immediately after having DD1 and DD2.

If I could find a surrogate, I'd have a truckload more but pregnancy is a complete nightmare for me.

Physically, I find it very challenging looking after DD2 (lingering issues from SPD plus a dodgy back to boot) - being pregnant AND looking after DD2 would be a complete and utter nightmare. Given my age, I think I've reconciled myself to 'only' having two. I feel very blessed to have DD2 in particular.
