Haven't had a period since September 2005 since conceiving DS, so we're at 22 and a half months and counting.

DS and I sleep in the same bed and it's a rare night that he won't feed once or twice in his sleep. He'll often 'miss a feed', though and still no AF. Especially during assignment times when I have to leave him with a relative, we'll go for a whole day without a feed, and twice a week he's in childcare on campus, but I don't feed him. I actually thought I'd get it back after two weekends ago when I was away from him and just pumped 3 times a day (he feeds so much more than that when we're together).
