We have one daughter, aged 8, and for a long time contemplated stopping at one. All our family thinks we've stopped at one. However, she is a very sociable and extroverted child, and as time has gone on, it's become more and more apparent to us the benefits of a sibling would have on her. So we're now trying to conceive #2.

It's taken us this long for us to feel that another child is right. Or rather, it's taken ME this long to feel it is right - DH would've said yes as soon as I indicated I was ready - But like he says, I'm the one that's got to go through the strains and 'work' of carrying a pregnancy, giving birth, and being the primary caregiver in those early years when they are more labour-intensive.

I don't think there is anything selfish at all about whatever you decide. However, for the sakes of your relationhip, can you take a wait and see approach? You might feel differently in a few years when Aneta is off to school and a bit more independent - or you might not! The important thing is recognising that somewhere in your relationship there will need to be a trade off or a compromise - on both parts.
