Sleep help for toddler with own bed!

[Qwertyguerty]

My DD is 35 months old

We moved house 4 months ago and she was still sleeping great and In her cot, 2 months ago she climbed out so the next day we replaced her cot with a toddler bed, in the same week we did up her room a bit and added extra toys and books for her to play with in the morning when she got up before us.

She got used to her bed quickly and loved it.

She used to sleep great, down at 7pm, up between 5.30-6am. When she got up early we could hear her playing with her toys and books and it went on like this for 3 or 4 weeks.

Then she worked out how to open her door and come into our room in the morning, which was fine we’d get up a bit earlier and start our day with her.

But she’d start getting up earlier and earlier, first 5 am for a while, then roll back to 4.30, then a few times at 1.30am and my husband, bless him, took it on himself to try get her back to bed, she’d only do it if he slept on her floor, then it stopped working, then we’d try having her on our bed, which would be perfect if she’d settle and sleep with us but she doesn’t.
She will toss and turn trying to sleep and get comfy but can’t, so after an hour DH will give up and try to get her back in her own bed, and failing this he will take her out in the middle of the night in the car to get her to sleep, which works but is not sustainable.

When I google this problem, all I seem to find is young toddlers in cot sleep training stuff which isn’t helpful when she can get out of bed and into ours.

I don’t know if it’s a type of sleep regression or if it’s the intense heat we’ve been having the last week or so, we’re in London. Getting her room cool is near impossible, we’ve tried iced bottles of water in front of a fan, ice cubes too. Closing all windows During the day to stop light and heat getting in, a damp towel, etc.

Also she still has a day nap, about 1.5hrs ending around 2pm or if she’s exhausted from a bad night sleep she might sleep till 3pm. However that’s not been an issue before all this started and shed happily got to bed at 7pm and wake up at a good time the next morning.

I’d really appreciate some help or if you’ve been thru the same and how you got thru it. She’s a great lil girl who listens to us and is happily guided by us but it seems to me that she wants to go to sleep but cannot for some reason. Thank you.

Gro clock and a reward chart?

We got one today and will start at the weekend, also gave in and bought an air con unit to keep her room cooler so here's hoping some of this will help

But I'd like to hear more suggestions if that's not too cheeky!

My 2.5 year old has just changed to a toddler bed after trying to climb out. We have resorted to a stair gate on the bedroom door which now means he goes to sleep at bedtime.. But he's still waking at least twice a night sometimes more and during the night wakings the only thing that gets him back to sleep is one of us sitting by the door of his room and even that doesn't always work.
Not much help but following for ideas

We have a gro clock... He managed to wake up the sun within 5 mins of us leaving the room

My DD dropped her nap at around 3 and even before she dropped it we found that if she slept more than an hour it effected her sleep at night.
We’ve always had a safety gate on DDs door as an extra safety measure so she’ll call to us from her room rather than come into us and I think because she then stays in bed when she wakes up it has made it easier to settle her back to sleep in her bed.
We had some issues with her getting up too early (before 6am is too early imo) and the gro clock helped with that.

My just 2 year old worked out how to wake up the sun too! 🤣😂 Had to move it out if his reach
