Bedtime battle

My 6yr old always yells, ‘no’ when we say it is time for bed. Even if he is given time warnings, etc, and even if he disagrees appropriately, asking for more time which is given, he fights us after the extra time has finished. He has older teen siblings who stay up later than him. He is furious he doesn’t get to stay up too. He feels like he is missing out. EVERY SINGLE NIGHT IS A BATTLE!

 

How do you suggest we handle this?

 

Thank you
