That's it really. DD has always been a bad sleeper but for the last few weeks (months? It's all a blur...) she has been getting up virtually every night, sometimes two or three (or even four) times. She usually just wants putting back to bed, which I wouldn't mind so much except that then I/DH can't get back to sleep and lie awake, sometimes for hours (partly because I'm anticipating her coming back, even though often she doesn't). The whole thing is then made worse by the fact that she's also an early waker (5, 5.30, 6 if we're lucky), so she's back at that time, after which point we let her into our bed and she often goes back to sleep for an hour or two with us - but I/DH don't, really, and as a result we're both almost permanently knackered.
I'm not so bothered about the early waking, largely because I know from experience (and from what I hear/read) that it's the one virtually unsolvable sleep issue. But the night-time wakings are a different matter. What on earth can we do? Is there any sort of sleep training for a 3-year-old? I'm absolutely certain she'd scream the house down, and I'm keen to do something more gentle, but on the other hand that's what we're doing now (carry back to bed, tuck in, kiss, sometimes stay with her for a minute, but literally only a minute) and it's clearly not solving the problem. For a long time I kept trying to tell myself it was just a phase, but it feels like the longest phase in the world.
The other problem is that DH and I are considering TTC no.2, but the thought of having to deal with a baby waking at all hours (normal, of course) on top of this just fills me with dread...
