Three months of awful sleep from my now two year old- please help, feeling a bit broken

[WannabeSurfer]

My second child is two next week. For the last 3 months he’s slept awfully. Prior to this, from around 8 months he would go to sleep by himself and sleep through- mostly.
Recently, he will only go to sleep for a nap (one a day, varies from 45 mins to 90) or st night if I am in the room with him and stay there until he’s in such a deep sleep he can’t hear me sneaking out.
If I don’t stay, he cries and shouts. I am comfortable with a couple of minutes but no more- and he has good staying power and is stubborn too.
Once he is asleep, he wakes once or twice in the night. He goes from fast asleep to standing in his cot jumping up and down, crying and shouting. He stops as soon as DH or I are in the room but would start instantly again if we left.
I know that little ones’ sleep patterns aren’t always great but this is a marked change to previously. He is our second child, and we have a third on the way.
Any help gratefully appreciated.

Sorry to hear of your trouble.
Not got any advice I'm afraid, but could this just be a developmental stage he will grow out of? Some sort of awareness of being alone? It sounds like he is capable of self-settling etc.
Alternativelt, could this be because he knows there is another baby on the way and is looking for some extra attention?

It doesn’t sound like he is frightened? Assuming he isn’t, I would tell him firmly that it’s time to go back to sleep, and then leave. Let him shout for a minute, go back in, reassure, leave again immediately. Repeat until he gives up. You may have to do it for quite a long time if he is stubborn but the next night will be much shorter and the third he will probably sleep through again. I did not enjoy doing this with either of my kids but they always woke up beaming the next day and then slept much better, which was better for all of us.

I agree I don’t think he’s frightened. Last night was horrendous. I feel broken. I am totally thrown as for the first time I don’t have answers or a way forward. I don’t think it’s a reaction to a new baby on the was as this started happening before we told the news.

Hi wannabe my lb was 2 in September I'm 30 weeks pregnant and he used to be a perfect 7-7 sleeper. Ever since beginning of December his sleep has completely changed he started crying when going in his cot and waking as early as 5. The lastest wake up we've had the past 7 weeks is 6.30. I used to cry it out technique for settling to sleep which worked but then the last week he's been hysterical when leaving the room. Last night he fell out of his cot and climbed out two more times in the night. He casually just walked into my room at 3am and got into my bed and went to sleep, I waited half an hour and tried putting him back in hiscot but he woke and instantly climbed out again. So tonight he will be in a big bed with his baby gate shut, i think I'm going to do the supernanny technique where I just keep putting him back in bed but I'm absolutely dreading it. My partner works away and isn't back for 2 weeks and I'm pretty tired being 30 weeks pregnant but it has to be sorted!! Just wanted you to know your not alone!!! X

My DD (20 months) is like this. No solutions but you're not alone. I am also broken

I can't add much but hang in there.... my dd slept amazingly from little THEN at 2.5 years it all went to pot!!!!🙈 it took six + months to get back to normal. At the time it felt like it would never revert back! We maintained routines and carried on as best we could. Thankfully it vvvvslowly improved
