My kids won’t sit still and it’s driving me insane

[Wotsitsname]

I can never relax and watch the television they are up and down like yo-yos, cartwheeling, dancing, fidgeting, talking, handstands, asking for things. I have no downtime. I run around taking them to clubs and sports activities but they still never give me any peace. One is 12 and the other 9 so they are not babies. Am I being unreasonable to expect them to sit still for a couple of hours in the evening to watch a movie or a tv show?

My DD is 12. She goes up to her room at 7 at the same time as her younger brothers. She doesn't have to go to bed but she is in her room reading or watching TV or drawing. In our house 7pm onwards is adults only downstairs.

Same 10 and 9, 9 year old is bad but they both trigger each other and it's like a whirl wind rollercoaster all day long... Youngest is on the waiting list for adhd, (dad is adhd also) suspect oldest is too but no where near as bad as the youngest so haven't done anything about it yet.
no advice except your not alone! I have considered buying myself and partner some ear defenders just to take the edge off the noise

My son is similar, He is ASD and sensory seeking. We put a swing in the garden, it really helps meet his sensory needs and calms him down. Might be worth a try?
