Sleep issues

Cracking up with both DDs over bedtime just now.

Dd1 is 4 next month and since around 18 months has always been fairly good at going to bed around 7.15-7.30 and asleep for 8. Dd2 is 18 months and was always great at going over by 8pm too. She absolutely loved her sleep.

Dd1 has started shouting constantly when we leave her room after we do her stories and songs. She will not stop shouting and it then riles dd2 up and gets her more restless or wakes her. We've tried giving her a book and letting her choose when she wants to go to sleep, tried one warning then the door gets closed so she doesn't wake her sister, I've tried reward charts and stickers and bribery with her favourite tv programme but nothing is working. She generally keeps shouting til well after 9pm.

Dd2 went down awake in her cot from 6 weeks and was always quite happy. When she was 8 months she started standing up in the cot and falling and smacking her head so I had to start letting her fall asleep in our bed first then transferring her.
This was fine and she was usually in her own bed by 8pm asleep.

For some reason, since around may time she will not go to sleep til 9pm. It doesn't matter if she's had an early nap, a late nap, a short nap or a long nap or no nap at all, she just will not go to sleep until 9. It's like a switch flicks.
It doesn't matter if I put her in the cot awake or cuddle her to sleep.

Both girls have a wind down routine starting around 7 once dinner is finished where we get Jammies on, teeth brushed, stories, songs, cuddles etc.

It's meaning that it's after 9pm before either hubby or I can get down the stairs and tidy up the kitchen and put toys away and then finally get to sit down (usually closer to 10pm) to actually speak to each other.
I'm a teacher and go back to work next week and I need to work in the evenings at home and I'm panicking about how I'm going to manage that if I'm not even sitting down til almost 10pm.

It's really getting me down having no down time with hubby or to myself and i know it's going to be even worse when I go back to work. I've no idea what to do about their bedtime.
