Mine are 7 and almost 5, too. School nights they are in bed at 7, we do readers (I do DD, DH does DS) then lights out at about 7.15 and we swap kiddies for a brief chat and cuddle. All teeth, toileting and drinks (very small water) are done before 7pm so there are no excuses!

That's on a school night... weekends are much more relaxed.
