I've got two - as you know - and don't plan to have any more. It took me a while to feel broody after no. 1 (now 6) and I definitely don't feel broody now (no.2 is 16 months). I find the baby bit (lack of sleep, trouble with feeding, slight loss of sense of self etc) quite hard so the idea of going through that again does not excite me!
That said, I have fond memories of the births of my two, and am a little bit sad that that part of my life is over. But I am looking forward to what's ahead, seeing how they will develop and so on.
