Toddler driving me mad!

[Crumpets4butter]

DD is a very very active strong willed high spirited girl. She is 2.9. Her sleep has been up and down in the lockdown period etc but at the moment doesn't seem to sleep longer than 9 hours at night ..and that's on a good night!
The last 2 nights she has screamed blue murder to go downstairs and nap on sofa, I say no but give in to her eventually as she screams at the top of the lungs and the neighbours already hear us argue too much (won't talk about this here).
Last night she only slept 10:30-5:30. She has a nap in the day, I've tried to keep her awake but then she will conk out in front of the TV at 4 or 5 which makes things worse.

I can I extend her sleep at night and help her stay in her room? She doesn't 'obey' her gro clock. I do the night wake ups and need some sleep as I'm on mirtazapine for anxiety and am exhausted. Thank you.

Didn’t want to read and run. I have a DD who is 2.2 and very energetic and strong willed. She’s currently sleeping about ten hours at night so a little better than what you are getting. I know this isn’t what you want to her but she probably is playing you now because she knows you’ll give in (I understand why you are though) can you be tougher? Maybe explain to the neighbours that they may have a few nights listening to crying? I think she’s old enough to understand that she had to stay in bed so try and be strong and keep her in her room. Take a pillow and lay with her maybe? Good luck

DS2 is 2y 8m and a "spirited" chap. He's never slept well - typical at the moment is 9 hours 19:30 until 4:30. He occasionally wakes in the night, occasionally sleeps til 5. He naps 1.5 to 2 hours in the day which I have tried reducing. Didn't help and made him grumpy all afternoon. Tried later bed times, earlier bedtimes, out of ideas now. He's started to wake DS1 up now so often they're both up by 5. Nothing useful to suggest but you're not on your own!
