She won't stay in bed!

[waitingimpatiently]

My (almost) 2 year old has been in a proper bed since January (around 16 months old) and has never been such a pain for getting out of bed until now.
We recently took her dummy off her and she was so good about it but it seems to have sparked something in her where she doesn't fall asleep as fast as she used to which means she constantly gets out of bed and messes. We can't just leave her in her bedroom to mess around because she has a changing table in there where, when we have left her, we've been faced with sudocrem everywhere or no wipes left in the packet, or she'll pull ALL of her clothes out of her drawers and sit on them etc.
I am 7 months pregnant so I can't face constantly running up and down the stairs to get her back in bed and I feel awful to let DH always do it too, and times like now, he works late so he can't anyway! I get so mad, she barely listens to me anyway and I feel awful but I get so cross with her when she does it because I feel like a broken record.
Please, someone, give me some advice on what to do to keep in her in bed, short of strapping her down?!

Take the sudocreme, nappies and changing table away if you can as its sounds like its a distraction for her.
As for the clothes, she will eventually tire of getting them out.
Other than that i recommend a good winding down routine, ie dinner, bath, milk, story then bed

Take away everything like wipes, Sudocrem etc and put a gate across her door - just leave her to it.

We employed a version of rapid return around the same age. The theory is that she loves your attention and input and doesn't mind if it's grumpy attention or not. So, when they get out of bed you just gently say 'bedtime', or 'night night' or whatever- one phrase, repeated each time, no deviation. You put her back to bed and say this as often as needed, very calmly. The idea is that without reward for getting up, she'll learn to settle down at bedtime.

Our DD was about 20 months when we did this. First night took 2 hours, second 45 mins, 3rd night was 20 mins and from there she mostly stayed in bed when we said goodnight and left the room. Every few months we'd then have a need to do a 20 min session again. My main motivation was that she got up at the same crazily early time, regardless of when she went to sleep so was just knackered with all the sleep time lost to faffing.

Whatever you choose to do, I hope you find a solution that works for you and soon.
