9 year old wants to play with me non stop!

[2013Mumma]

My 9yo son is pretty independent in most things. He is lovely, funny and fun to be around. He is an only child and I have always been a single parent to him, I work full time and have a sleep disorder which leaves me exhausted most of the time.
My boy wants me to play with him all the time, every 5 mins he's asking me to go out on the trampoline, play basketball, kick a football around... He has so much energy and I have so little. For context, he is busy with clubs after school and on the go most of the time but when all of this is done he is so dependent on me for play! I play with him everyday, normally multiple times but it feels more and more that I am saying no, I cannot play with you right now. I dread evenings where we are home and 'Chilling' as there is just no chill! I've just talked to him and explained that lots of other mums aren't spending so much active play time with their kids and that he needs to find things to do alone. Now I feel guilty!
Any advice on how other busy mums handle this would be hugely appreciated!

Is there any other children who live close by who he could become friends with?
If not you could organise lots of play dates so he has someone to play with.

Can you find something you would enjoy watching together? That way you get a bit of a rest but you're still doing something with him. Will he sit still long enough for that?

He needs to have friends or neighbours or cousins about to work his energy off on. I am in a similar situation with DS(7) and I basically have to ensure lots of company, besides playing way too many board games.

Sometimes you have to let them be bored and amuse themselves. Seriously it's important for their development.

My DD never did independent play or play with toys, so it was torture when I just wanted down time. I'm a low energy sort and not good at playing with kids so it was always tough for me especially the weekends. Luckily when she was about 3 we moved to a new neighborhood and she became really good friends with two of the kids that lived nearby and she would play with them every day after school and all day long on the weekends, it was a godsend. Honestly I don't know what I would've done if we hadn't moved, probably send her to live with her dad (just kidding... a little! 😂)

Get him a nintendo switch, he'll never want to play with you again

Of course it is fine to encourage him to play independently and to amuse himself. An important skill.

I feel your pain. My son is 8 and never stops. I am pretty active myself but his energy levels are beyond my limits. Most of the time we have some kind of planned activity/sport after school, but this week things are cancelled and the prospect of 6 hours between school and bed time is daunting. When I have him over weekends when friends are away it is exhausting. No solutions here but you are not alone!
