I don't even know if this is unusual but I just went upstairs to get ready for bed but I check on the kids every time before I go to sleep. It's become such an embedded routine that I find it hard to settle if I didn't or if I forgot, I'd lie there, get up and check on them, then I can go to sleep peacefully as if I know everything is ok.
My eldest gets a couple of kisses and I tell him I love him, youngest gets a stroke over his head and me telling him I love him (he's still in a cot, otherwise he'd get a kiss too). They're 4 & 1 (almost 2).
Do other parents do this or is this just me?
