I can only assume that him behaving like this is a direct result of moving home. Before when you moved he may not have been at an age where he could react, wander about, reach the door handles so if you can imagine what its like for you in a clothing store, you look at everything, want to hold everything up...hes feeling the exact same oh this is new, look at these handles, oooh I have no furniture I can run around around in circles etc etc. I know you say you have tried everything, but he may have became confused with what you actually want from him as you have only given him three weeks to adjust to a new home and all these different techniques to get him to sleep, it all sounds very paniced and stressful (which I can understand having been through sleepless nights myself) sort of like oh no hes not sleeping lets try this, until its gets to teh desperate pint where you find yourself trying something different every couple of days. Hell be thinking well shoot mom last night we did this but now were doing this.
Hes trying to adapt to big changes and your adding to those changes< While hes in the bath remind him again ie after this well read a story then go to sleep. When you leave the room shut the door behind you. If he comes out pick him up give a cuddle and say its sleepy time or whatever you prefer. Next time he comes out no cuddle just its bed time. Next time say nothing just guide him back to bed. He will scream to high heavens, you will become stressed and it will be a long night but HE WILL get the message, he will not want to do this every night trust me, it might take a week, it might take a month but it will work (if you persevere it won't take this long) after two nights if its not improved don't be disheartened it just simply means you have a stubborn child lol that willing to get the better of you, don't allow him too. Alternatively you can stay in the room with him, don't sleep beside him just sit by the bed and turn away from him, give him no attention and only get up when you have to put him back there. Move away from the bed gradually he will get up to see where your going but just repeat it. I know its tough but it will work out! Good luck:).
Maybe do the quieter time, bath, dinner, teeth and story routine (or whatever you do) and have him in bed an hour earlier than you normally have been if he is getting over-tired. Maybe get a dim night light and leave a couple of small toys he can play with in bed with him. Don't lock him in and if he gets up, keep putting him back into his bed with no reaction emotionally.
He will learn that he is not going to get out of bedtime, even if it takes a while. Could it be that there is new furniture or something like that that might be scaring him in the new place at night? Maybe if there is and you can fix it, that might help too.
Good luck.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
