DC (10 & 8) are (temporarily, thank god) sharing a room and bedtimes are a fucking nightmare. Neither will go upstairs to bed (only one room - theirs - is upstairs) without the other one or without either me or DH. If we do manage to get them up there without us, they start physically fighting.
DC1 really needs a later bedtime than DC2, but their light has to go out at the same time (8pm). Sending them up separately just draws the whole process out.
They ALWAYS pick fights with us at lights off and/or start manufacturing various woes, fears, etc. DC1 in particular. We've tried it all - validating feelings and letting them talk (just means that it adds 30 mins after lights out before they're settling), being stern (everyone ends up arguing with each other), ignoring them (they just get louder).
To add to this, they insist that one of us sits with them after lights out. If we refuse, they kick off and the whole process takes longer. If we go downstairs anyway, they will inevitably come down multiple times complaining that we're too quiet/ too loud/ they can't get to sleep.
Neither threats nor rewards work to stop any of this.
It is driving me IN-FUCKING-SANE. Bedtime takes forever. I'm frazzled by the time I finally get downstairs (usually after 8.30) and end up staying up late to get all the shit I need to get done of an evening.
Any wise tips on managing bedtime better?
