We're currently contemplating trying for DC2 and making a final decision whether we go for it by end of this year or stay as a one-child family.
I'm no spring chicken (mid 30s) and while I know lots of women conceive later (power to you), I don't think its right for me.
Understood everyone's reasons are different and what is right for one person may not be right for another but I'd love to hear what was the reason you chose to have another or to stick at one.
