What am I doing wrong? 5yo

[SleepingStandingUp]

Home schooling the 5 yo, he doesn't focus, he doesn't concentrate. If I can get an explanation out of him it's just nonsense "why aren't you listening?" "because of that" and will point at something random rather than give an answer. We'll do a sum and 2 secs later he just sits and stares blankly when I ask him the same sum. I feel like he's really regressed. He doesn't listen. He doesn't pay attention. He won't look at me when I'm talking to him.
That was it. Me: why can't you look at me when you're talking to me? Him: because of this (points to random play mat). He does that kind of thing a lot.

We had been told because of his o2 and amount of time in hospital etc he'd have some sort of learning difficulty but once he started talking (about 3.5 years) he came on really well in reception and was mid tier for everything so I assumed he hasn't but maybe this is part of it? Or I'm just a shit parent? Or he's just naughty?

And I know people will say don't do school work and just do creative play all day but with needy 6 month old twins fed 3 hourly, and DH working full time, DS shielding and me not driving, I can't get in the kitchen to bake with him, get outside with him (weather crap but also both babies allergic to something in the garden), we haven't got the space for big crafts, the babies don't nap v long in the day so there's no real time for that stuff, even getting the paint out 2 babies are screaming and DS is bored. At least with school work it's structure and he won't be massively behind come Sept

Thanks, that's it, he's worked so hard to catch up, he's still behind on speech, behaviour and toileting, but as long as academically he was average I thought it meant the rest would catch up. I'm scared if I let him regress we'll lose it all

Let him play with your twins and learn other important skills. There is a good reason why much of Europe don't make their kids go to school until 7. It sounds like you are doing amazingly, but it will only cause you stress if you force him. At five, he is still very much Early Years. Leave him to learn concentration skills himself by offering him loose parts, little objects, construction toys, mark making paints pens etc. There's a lot going on in their brains when they get into a deep state of play. Sadly many schools are pressured to get results and don't allow this to happen, I'm a mum of 2 boys, childminder and doing a masters in childhood and youth. I worry that we are making our children stressed from an early age. My son (6) went back to school today and is doing less "work" there than at home - he had also stopped listening/concentrating with home school stuff. I know how you feel xx
