Struggling with motivation due to disrupted sleep

[Lavender14]

Anyone any advice?

Ds 3.5 seems to be having a real sleep regression. This last month he's been absolutely fighting bedtime so bedtime is taking from 7.30 until 11.30pm. On the couple of nights (only maybe 3 nights in the past 3/4 weeks) when he does go down well he is waking up at midnight for a pee and then not going back to sleep until 2.30 or 3am. He's so tired he's almost falling asleep in nursery. I've tried earlier bedtime, later bedtime but it makes no difference. This in itself is fine I know it's a stage he is going to need to work through, but what I'm struggling with is the bloody housework. Usually I'm on top of everything and do a clean after he goes to bed but now it's either too late for me to start, or I'm so completely drained that I cannot find the motivation and only do the basics to keep us ticking over. I hate it, it's important to me to feel like I'm on top of things because I don't have much support around childcare so I don't like feeling as if I'm on the back foot with the house because I know how it goes if one of us gets sick etc. I was really hoping to go into the bank hol on top of things so I can just enjoy the time off work with him but now I'm going to have to spend my whole morning catching up on cleaning and after another night of only 4 hrs sleep all I want is to lay on the sofa and stare into space. I usually function pretty well on less sleep but because it's been so sustained I'm really starting to struggle.

First things first - does he have proper black out blinds in his room? Is he getting too hot? Has he been unwell? Is he weeing more during the day as well? If so I'd get a GP check just to rule out diabetes if he is up a lot in the night to wee.

Is he upset when going to bed, or just restless? Can you leave him listening to a Tonie box while you do some housework and pop up at intervals to check him so that he knows he's not alone but you're not right there all the time?

Yes proper black out blinds in the room though he doesn't like it being too dark so we have a little night light. He usually kicks everything off as our house is fairly cosy so I don't think he's getting too hot or cold. He's always been very good at tucking himself back in/ kicking off blankets if he got uncomfortable and going straight back to sleep. No illness, I actually thought maybe he was taking something at the beginning but nothing materialised. Not weeing more than usual, he does drink a lot but he runs warm and is quite sweaty so that's not abnormal for him. He was checked for diabetes a while ago and that was fine. No other signs. He moved to being dry at night a few months ago and this kind of coincided with his sleep starting to go a bit up the left though initially that was more waking up in the night too pee and then not being able to get back over. Its only one wake up in the night not multiple but then he's wide awake.

He's restless and clingy, doing everything possible to postpone bedtime even though I can see that he's really tired. He doesn't want to be cuddled to sleep and doesn't want me beside him but also doesn't want me out of the room which again I actually think is a delaying tactic. We don't have a tonie box, could look into one but I wonder would the noise not keep him awake?
