2yr dd makes herself sick at night, crying, and vaults over all obstacles in her way...

It's like someone has flipped a switch inside her in the last couple of weeks. She was never a great sleeper but we have had around 3 months of pretty much perfect sleep, until 2 weeks ago. In that time she has vaulted over the side of her cot twice (now taken sides off and she is in cotbed), made herself sick on several occasions with her screaming and crying to come out, vaulted over the gate on bedroom door (will have to come off today), wakes up numerous times every night, disturbs ds who sleeps in the same room. She ends up in our bed most nights as I am seriously short on sleep and it's the only way to settle her, although even then she often kicks, wriggles and stays awake for ages. Does anyone have any similar experiences ? Have tried CC (makes herself sick), gradual retreat (does work for a bit but then she wakes again).
Any shared experience/tips most welcome. Ta

My DD has just turned 4 and I have had several phases throught her 4 years like this. Months of settling no problem - then a spate of bad settling. Going through a phase now (just started nursery - so suspect that's why)- and the only way I can get her to settle is by leaving her door open and promising to go in my room and lie on my bed (watch soap!) and then go back and check her in five minutes, then ten minutes, then fifteen minutes - by which point she has fell asleep and I go down stairs. I know my DD is older - but you could try similar. I can't leave her to cry as she makes herself sick and gets in such a state - there is no way she would get to sleep.!

Jaynerae, thanks for your message. I have managed to get dd to sleep using the gradual retreat method - ie staying by the bed and moving away slowly, and she seems to take to this fairly well. The only problem is that this only works sporadically and she will then wake at say 11.30pm, and from then on it's broken sleep for the rest of the night - waking frequently (well it was last night anyway). I am waiting for a bed guard to arrive as she has fallen out of bed a few times and woken, so this might make her feel a bit more secure. To be honest she seems petrified of me leaving her, and gets herself into a right state some nights...
