430 wake up everrrrrrrryday

How do I change this?

This isn't sleep regression, he's been like this for so so long now. Plus he he gets up at least twice over night.

I have tried to just leave him but he will scream bloody murder until we get him - longest I've managed is half an hour and that's going back and forth putting back his dummy (paci) and making sure he's ok. We have also tried keeping him up later which didn't work either.

He also only takes two naps which aren't long at all.
