I think dd2 is scared of the dark. It's come on suddenly, she's always gone to bed fine before.
Now she wants the door fully open, and the light on outside, plus door through to landing open too (there's a dressing room off landing, which leads to bedroom). She sobs uncontrollable if any of this isn't done.
Problem is, she shares with dd1, who doesn't want the light on, and wants the doors closed (as they always have been). Dd1 is ASD, and has recently got over sleep issues, and so we are keen not to rock the boat.
So, wwyd? Either way one of them is going to be upset.
Don't think either of them would like to be split up.
Oh, dd1 is 5, dd2 is 3.
