getting a bit desperate

[Peaches2018]

Hiya Mumsnet!!
I hope everyone is doing well in this heat today with lots of ice creams and cool drinks!

I'm a bit at the end of what I can try and it feels like I'm only going backwards instead of forwards. Have a DS (1) and he slept fine till a few months ago. Then he started to wake up at 3 or 4 instead of his usual half past 5 or half past 6. Then he changed his own bed time from 7 to 8 of 9 even and he managed to go to sleep at 10.30 a few times too In between he's started now as well waking up at 3 in the morning which results in me taking him to the other room to get him back to sleep again.
I've followed a few tips from the No cry sleep method, I tried to do the shush pat (woke him up more and angered him) and I even tried the controlled crying for a bit over a week.... Not sure who was more upset: DS or Me.
I notice especially the last week or so he's more tired due to the lack of sleep, and when he is obviously tired and he's put it bed it seems he's downed a kettle of coffee and starts off in his cot bed.
I tried leaving him in his cot (crying only gets worse) trying to calm him down (doesn't work) and I end up now taking him downstairs again for half an hour or 45 minutes so he can burn off more energy. Then when he's going up again he starts crying in his cot which results in me taking him out and him falling asleep on our bed and being moved to his own bed
I'm not sure anymore what to do, how I can fix this or how I can turn this for the better. It starts to affect me now too with too late bedtimes, then broken up and a lack of a few hours of sleep together that I can recharge my own battery a bit. Any help or advice is very welcome

Hello to you!
Out of curiosity, when you let him cry, how do you do this? Do you go in after certain times to reassure and stick to it?

Hi, my 1 year old has suddenly started waking at 3am too! It could be down to the heat at the moment. It could also be teething- mine has 4 coming at same time! Interestingly she's suddenly really hungry too- tried her with a bottle and she polished it off in seconds. You could try that, to give the bottle in the cot, and then pop the soother back in. Really don't want to get back to night feeds but if they need it for a while in the heat, then maybe! Or just a bit of a sleep regression... which hopefully will pass.

@MummyToABoyy Hi I set a time (30 seconds then 1 minute etc) and went in to comfort him but it didn't help too great. I started this at 10 months and maybe that was wrong I don't know. At the moment my DS has figured out if he cries and look at the cam he knows I come upstairs. He also figured out that if he wakes at 3 and keeps on whining and crying I'll pick him up and move him to the other bed and sleep next to me (after he's been awake for an hour and lolling around on the bed) He has one nap depending on what time he wakes up for about 1 hour to 1.5 hour (he often wakes up after an hour) and I don't let him sleep anymore after 4.30 because otherwise he'll be going to bed the time I go to sleep

@Mammalian Hi in the evening in his cot he suddenly does want to drink a bit more and one molar partially broke through (my husband says to give Calpol or Nurofen before bed but our DS doesn't seem in pain and I don't want to make that a habit) but it's been going on a bit longer (my bags under my eyes are proof of that )
I keep a sippy cup in our room too and the window is open at night to cool it off a bit. Hopefully the waking up way too early will pass for us
