3 yr DD not going to sleep and waking up in night.

[Hollian]

Up to 4 months ago my 3yr old DD slept all night from roughly 7pm - 7am (with a small 1/2 hr variation each way). She is now refusing to go to sleep at bedtime and she also started to wake up from 2 to 8 times a night.
She has the same bedtime routine - tea, bath, little bit of TV, supper & milk, story and in her cot awake. (I tried a cot bed about 6 months ago - disaster - so back to cot).
So far I've tried reinstating day time nap, rewards, nightlights, groclock, going in every 5/7/10/12/15mins. None of it seems to work.
So last night I made the decesion to sleep on a mattress on her floor. She fell asleep with me on the mattress at 7.30, went into to her cot from 1am -3am and was unsettled, then back to the mattress with me until 730am. She slept well with me on the mattress.
We both got a better nights sleep, but what do I do now?
DH is not happy I slept in her room, but both DD and myself needed a good nights sleep.
I want DD to be able to fall asleep on her own at bedtime and if she wakes through the night. And I want to be able to sleep in my own bed all night!
So anyone got any ideas what to do next.

bumping you as I have similarish situation and no answers! I've recently had a baby girl, and dd1, nearly 3, is lovely with her, but I think the reaction to this is coming out with pushing boundaries with me. we've always struggled with her sleep in all ways, and maybe she knows this is a stress point for me, so that is where she chooses to push. I can't help feeling like there is some insecurity in with it - she tantrums most nights about going to sleep - even if we've had a lovely day and she's tired, and wakes most nights to come in our bed. Can you identify anything that's changed in your dd's world? your situation seems such a contrast to her norm - maybe some health issue?

Or maybe as she was always so reliable before, now she's a bit older and just needs a change of routine - more independence? i sometimes wonder if I over egg the whole going to bed process - it takes too long from start to finish. I also realised recently that some of her resistance -and oo I think I'll get really over excited and play lots now at storytime was because she was bored of ALL her books - so I've finally started using the library card we've had for ages and that helps.

feel for you though - it's horrible isn't it - and the lack of sleep really doesn't help.

Helps to hear someone else struggles too.
No new baby here, wish there was!

DD had a bad sick bug in April and was very ill for about a week. Her sleep has been affected since then.
I did wonder if she needed more independence as well? So tonight we have changed her cot into the cot bed. She is very excited! Rightly or wrongly, I'm going to sleep on the floor beside her tonight.

She slept so well with me beside her last night - she was only up once and then an early start at 5.15am

Is she having an afternoon nap? If so, drop it.

I also think she should be in a bed. IMO children shouldn't be in a cot once they are capable of climbing out of it. It's dangerous.

DD stopped regular afternoon naps just after she was 2.
She usually is in a sleeping bag, and has never attempted to climb out her cot.
She's never really been much a climber.
