I'm really, really struggling with my 2 year old (28 months if it matters) and his sleep atm. He has always been low sleep needs and can't sleep more than 11 hours in 24 but also absolutely cannot stay awake a full day without a nap. He will be up nearly bang on 8 hours after waking up from his nap so unless he's asleep by about 11 (and so awake by 12) we have a horrendously late night. He often sleeps around then with us but when he's at childcare he sleeps later. We've asked them to wake him up no later than 1.30 now regardless of how long he sleeps cos we just can't cope with 9, 9.30pm nights where he's absolutely full on until then.
We're capping him at 45 mins in the day but he's furious and miserable when woken up; he'd like to sleep for an hour which has been how long he's napped for in the day since a baby (obviously when younger it was multiple hour long naps in the day rather than 1). I'm considering just forcing him to stay awake the whole day but when we've done that before he just falls asleep at like 5 or 6, wakes up an hour later and then it's even worse. He's also really intense and absolutely full on and full of energy until he's asleep. We have no tv on in the evening to try and not over-stimulate him, have dinner and a long bath (cos he loves it and it keeps him happy and occupied for ~30-45 minutes) and g out for a walk / in the garden when we can to try and tire him out too but recently he's impossible to get dressed. It took 45 mins to get his wellies, hat and coat on last night cos it was raining and he was wild in the house and we just needed to get out. He was absolutely full on until 9pm when he finally went to sleep. We usually go upstairs a little bit after his bath (so around 7.30pm) and read / play with blocks / attempt to wind down with the lights down. He's often fine playing there but can keep going for so long until we're both exhausted. There is NO WAY he would go to sleep earlier if we went up at say 6; we have tried this, he's just furious, screams to go downstairs and regardless of whether we force him to stay up or do go downstairs goes to sleep at the same time. He's not over-tired, he's just not tired; it's like we're trying to put him to sleep at 3pm in the afternoon and he has that kind of energy. He only eats sugar if we're out at a cafe or a biscuit at a playgroup etc., not as a daily thing.
If anyone has any advice to cope please I'd be really grateful; last night I was nearly crying I was so exhausted and frustrated and snapped at him really horribly a few times which obviously made me feel awful. I just get past it and go really cold and detached with him to just function and I'm really worried how damaging that is for him while also being absolutely past it and have no idea how to fix this. My DP and I both work full-time and having him wild until 9pm each night is beyond draining.
