Beckles, IKWYM, hence I gave the concept away pretty quickly. When I did first try it, it was after my babes had kind of established a vague 3 hourly pattern of feeding for themselves....(literally, I could time Charlie, his demands for boob were like clockwork!). So I figured that if his last feed was at about 7, then he would likely want to be fed again at around 10pm ish.......but no, he quickly told me he wasn't interested!
