We are ttc number 3 after much talk of whether it is a good idea or not. I've been very keen for a third, my dh less so. In the end we have made the decision to try as my desire for another is much stronger than his desire not to.
His reasons for sticking at two are very sensible - easier life (cars holidays etc), cheaper, life has got easier (youngest is 16 months) so a reluctance to go back to sleepless nights etc, not being outnumbered!
My reasons for a third are pretty much just that I really really want one and I struggle to give any more tangible reason than that!
So I'm interested in what were your reasons for going for the third child?
