Every single night without fail is a nightmare with my 7yo. He starts messing about with his brother (brothers sleep together) and always takes a while to go to sleep. Most nights it end up a shouting/screaming match as I'm getting fed up of it. He's also started asking to sleep with me again but don't want to go down that route again as I think he should be able to sleep in his own bed on his own by now. Any tips would be appreciated.
