DD is 9 weeks old and nearly 11 lbs - she is currently sleeping from 7pm (last feed) to between 2 and 3 am for the next one. She then sleeps happily until around 7am the next morning. So here is the dilemma - should I wake her at 11 or midnight for a feed ? She hates being woken up and will take very little milk if woken and so will generally wake again at around 5am - so should I wake her up anyway or let her lead?
