My son turns 2 next weekend. When I'm off work, he has milk when he asks for it, as long as he's already eaten... usually in the morning, before a nap, and once or twice max at night or not at all at night (like last night, when he slept without waking until morning, then had some in the morning.)
I didn't get my period back until September. I'm not sure if it was a period I ovulated for or not, though.
