Sleep begets sleep. Although, my breastfed babies (got 4 of them!) were all still waking for at least one nurse in the night...it is considered developmentally normal at this age (I have an 8 month old son myself who still wakes once a night to nurse. He goes to bed at 6:30pm, wakes at 2am, sleeps till 6:30am. Naps from 9-11am and 1-3pm. It works for us, and also follows Dr Weissbluth's advice on an earlier bedtime...circadian rhythms being what they are, sometimes babies sleep longer and better with an earlier bedtime.
