My son is close to the same age and no way he would sleep at 730 he sleeps at about 9
We homeschool the rest of my kids so or schedule runs later then most peoples but hes exhausted by then more so if he has no nap were at an in between stage

Try reading him a book. Or try white noise stuff animals.

You just need a be consistent every time time he gets up put him back in his bed you tell you love him and good night the 1st time and then the 2nd time u tell it's bedtime good night and a 3rd time don't tell him anything I just put him back in bed if you keep doing it and he will finally fall sleep and get used to it you can also stay in his room with your back towards him and just keep putting him to bed it be tuff for alittle but he get use to going to bed by himself and in his own room I saw it on that super nanny show it seemed to work

How old is he?

It’s hard mine complains about our son sleeping with us so I’m tryna break him probably should have done that a long time ago I make him sleep by himself sometimes cause I just need the break

My son is the same way he’s three I’ve been tryna figure that part out myself.!!!!
