We have one 8 year old. We-re in SPain, so very strict lockdown here. DS has been fine, like a pp a little frustrated when we're both working, and he HATES his schoolwork with a passion.
But he was doing the Lego Challenge with two friends and his cousin, so daily videos to compare what they'd made. Every Sunday he plays an online game with his cousin in NZ, they've never actually met but have developed a lovely relationship with this. They play at the same time while comandeering my phone to simultaneously whatsapp video each other.
He's done a handful of whatsapp calls between family/friends, but unless they're all doing something (roblox, chess, Bingo with my dad!) the calls are rather boring for him.
It's got better in the last couple of weeks as we're allowed to socialise with 2m distance. He's been to the beach a couple of times with his BFF, bike rides/scooter through town. This Friday he's going to a friend's house with a pool to splash each other stupid!
He is a very secure little boy, used to entertaining himself. But we've also been playing boardgames as a family, reading, making crap with old boxes, baking, housework etc. Or just watching a film together. He is very sociable but has seemed fine staying at home (no real bloody choice!) and i'm sure he'll get back into the swing of things with friends and school once all this calms down.
That's not to say he hasn't had his pissy moments, mostly surrounding schoolwork or trying to get him off minecraft. We have no outside space (flat with no balcony or shared garden), but a nice view of the sea so he's spent nearly 3 months spying on boats with his binoculars and drawing flags
