5am every morning 😫

My toddler has started waking up at around 5am every morning. He’ll start crying and will not settle back down for anything. I’ve taken him to my bed a few times so we could just get some sleep but I’ve put a stop my that now as he was waking up asking to go in there. The other thing he wants is the string on joggers etc- he’ll sob and scream until he’s holding some, which is just too much as well. I won’t put up with him screaming and hitting because he wants to hold string and can’t 🙄

I just cannot cope with it. I’m beyond exhausted. I’ve tried going to bed earlier but I can never switch off before 2am for some reason lately, probably because I know I’ll be up soon.

Any ideas why this could be happening or what I can go to get him back into a routine where he’s waking at 7am instead, like he used to?

Thanks!
