Thanks everyone. Gee, it sure varies, doens't it. Both my boys slept through the night from an early age (DS1 from 8 weeks, DS2 from 3 weeks) but it apparently hasn't affected AF where I'm concerned.

What I didn't think to mention initially was that I went on Clomid to conceive DS1 because my cycle was up the putt. And that's why DS2 was a surprise package.

I'm not particularly concerned I haven't had AF yet, but in another few months I'll head to my GP to see what she reckons. I'm not inclined to seek assistance to conceive another baby (nothing beyond Clomid, at least) but if we're to have another baby I'd like it to be soon-ish only because of my age.

Thanks for your responses : )
