Three year old dd has slept through from around 9months old. Obviously since then there was the odd wake up which was fine and to be expected when you have children.
Recently though her sleep has gone all weird. She's started waking up in the middle of the night and then staying awake for up to 2 hours claiming she 'can't sleep'. Although I have found sitting next to her bed paying her no attention whilst she lies there helps her dose back off quite quickly. It's either that or waking up really early and refusing to go back to sleep. Which in turn up dd2 as well who is then grumpy because she's been disturbed. Dd2 still wakes through the night anyway so sometimes it means I'm having to go backwards and forwards between the both of them and by the morning I'm really, really exhausted.
She went through a phase a few months ago where she would wake at 5am and still be obviously tired, we bought a gro-clock to combat this and it worked like a dream, how ever now she just completely ignores it despite us reading the story that comes with it and explaining to her how it works.
She doesn't really nap anymore, maybe once every few days and she's usually in bed for 7pm and asleep within 10/15minutes.
She turned 3 a couple of weeks ago. Is there some sort of regression or growth spurt around now? It's hard but I can manage, but it would be nice to know that there's a reason for it.
