Can u limit the babies sleep during the day, or push his bedtime back a little?
Maybe only a small drink bottle of water for the 4yo so he isnt stomping around at 4am waking everyone up for a drink. Limit fluid intake before bed and make sure he empties his bladder. If its that bad, maybe go and wake him before u go to bed to use the toilet, then u mite be able to leave a drink for him without the concern of him wetting through? That mite stop the 4am wake up.
I assume putting them in seperate rooms isnt an option?
