Parents with a 6 year age same sex age gap.. help me out please

[Sakeofpete]

Do your children play together? Am I being unreasonable to ask Ds 11 to play with his brother Ds 5..
They get on so well mostly but Ds pesters Ds11 to play and I've said if Ds11 just gives him half an hour he'll then float off and play something else and Ds11 can escape.
Seems like we're having more battles with it recently but Ds 11 gets plenty of time to be with his friends, play in room alone etc so I feel like giving up 30 mins to play with your annoying little brother isn't so much to ask.. AIBU?
Or anyone got a better way to approach it?

To be honest OP from your update it sounds like they already play together nicely, so I wouldn’t try to force it any more. The younger ones have to learn as well that they can’t always get what they want!
