D.P.
S.,
Look at it this way: clearly this is not working and it is upsetting the entire household.
O. easy option: YOU do bedtime and trade a few other chores with your husband. I'll bet he'll take that trade.
Seriously, is him doing this O. thing SO important that its worth upsetting everyone in the house? Sounds like you're not getting your 30 minutes anyway.
Have your husband take over weekend breakfasts, so you can sleep a little bit.
Is this their father or stepfather?
