I have a son of 12 and a daughter of 9. They both go to bed at the same time only because if my daughter goes up to bed earlier she will be up until my son goes up anyway and will keep getting up.
When their dad is at home my son will call my daughter into his room so they can talk and my daughter will then refuse to go back into her own bed. The only way for me to get my daughter to stay in her room and for my son to stop talking/calling her into his room is to shout at them both (which I hate doing) but saying that my husband shouts at them as well (which he hates doing as well).
I have tried talking to them both in the mornings about their behaviour and they promise they will change but they don't. I have also taken things away from them, stopped pocket money and done reward charts as well but this doesn't work.
Any help from anyone would be much appreciated.
(As I said they only do this when their dad is at home).
