My DD is 21 months and has always slept through apart from the odd night. But, over the past couple of weeks, she's been waking at 2a.m shouting for daddy. Daddy goes in, cuddles her back to sleep and off she goes, until 2 hours later and the whole thing is repeated. I'm worried now that her bodyclock wakes her, and of course, we alter the clocks this weekend... How do we stop her waking?
