Terrible 1s / no sleep - HELP!!!

[PeachyGreen]

My 22 month old has always been a terrible sleeper. We’ve co slept, never sleep trained as I don’t know how to and what usually happens is I get her to sleep in her cot (stay in the room for almost an hour) and then she’ll wake up and I’ll transition her into my bed.
Well recently there has been tantrums, screaming, crying, back arching whenever we put her in her cot. She seems tired but wants out of the room. This lasts from anywhere between 1.5-2 hours every night. When she eventually gets to sleep; she’ll wake up at 1/2 to come into the bed. I am shattered. I get no down time.
just for a bit of background; we both work full time so evenings look like this:
5.30 nursery pick up
6-6.15 home
6.45 dinner
7.10 ish - bath & pyjamas
7.30 bed
Settles at around 8.30-9 finally.
what are we doing so wrong?

Does she nap at nursery @PeachyGreen? I’m wondering if being overtired might be a factor?

And are your evenings rushed or do you have some time with her for things like a massage and before bed?

It sounds like she's grown to prefer your room to hers and knows if she wakes or makes a fuss that's where she'll end up.
I'd be tempted to sacrifice yourself for a while and when she wakes, settle her in her room and then put her back in her cot. You could, if you're able to, get a comfy chair and when she wakes up and starts being upset, go in, take her out if she won't settle with you being in the chair and hug her for a while until she's calmer. Then try putting her back in to the cot.
Do you get her out before she gets worked up, or do you leave it until shes obviously upset?

Thank you all for your comments! The evenings are slightly rushed as we’re trying to cram so much into so little time. We leave her in the cot to get upset while we sit next to it and she’ll just cry and scream until eventually we either get her out or leave her in there until she gives in (while still sat next to her). In the night she always comes into our bed but think I may need to start putting her into her cot. Do you think a toddler bed would help with sides up?

you need to make her room cool (18-21C), dark and quiet. This is most optimal for babies sleep. If you can't make her room cool enough, then you need to dress her appropriately. Children (and adults) best sleep in cool room.
Another thing that might happen is that your baby got a nap before she left the nursery, so she doesn't need to sleep at 7:30. You either need to put bedtime later in the evening or tell nursery to not let her nap right before she leaves nursery. 1 year old needs 11-14 hours of sleep - including naps, so you either need to cut naps or cut her sleep time in the evening

What you should have done is to sleep with your baby in your baby room. You can try sleeping in your baby's room untill she settles into her room.

My son is the same age, and our bedtime routine is more like:

6pm - dinner
6.30 - bath
7 - out of bath, stories and put down 7.15, sings himself off to sleep at 7.30.

With her bedtime battles, your daughter will probably be really tired by 7.30. Is there any way you can get her fed and bathed earlier so she has a chance to properly wind down? Use a slow cooker to have dinner ready right away/pepped meals?

I'd always work on the "when" of sleep first, before the "how".
