Is your youngest DC growing up too quickly?

[user1483390742]

My youngest DS aged 10 (3 older brothers ages 18, 16 and 14) is growing up way too quickly and i don't like it!
With 3 older brothers, he seems to have missed out on all the kid stuff- Pokemon, CBBC, Match Attax cards. He is only 10 and wants to watch Youtube, Youtubers having boxing matches and asked today for a Depop account to buy/sell stuff online!
His brothers all do these things and it is impossible to stop him from being aware of such grown up stuff. I feel that he has nothing in common with his classmates, who like more age appropriate stuff. He would much rather hang out with kids 2-3 years older than him, which i do not allow. He is Y5, wanting to go to the park with Y7s and 8s!
I don't really know why i am posting. Things at home are how they are...i suppose i am just sad that he never had a chance to have more age approptiate interests.
Anyone with me on this?

Well, a 4th dc naturally has different experiences from a dc1 or even dc2.
From time immemorial oldest dc have always felt hard done by and restricted when they see younger siblings getting to do things at a younger age than they did, and older siblings have always dgreed the youngest sibling to be spoiled when their perception is they always got hand me downs and weren't allowed to do what older siblings do.
It is going to be a different experience growing up with older or younger siblings, bt it is what it is as far as I'm concerned.
What they gain in one way they lose in another.
