Yes, one of my almost 3 year old twin grandaughters is nocturnal and now has a separate bedroom so as not to disturb her sister. She has blackout blinds in her room, goes through a good bedtime routine, toys get put away, time for a milky drink and a story downstairs before going up to brush her teeth and have another story, then she's tucked in and settled down with just a landing light on outside her closed door. Minutes later she's asleep and by ten she's awake again and playing in the dark. They don't engage with her when she's tucked back in bed, and after 3/4 months of this, she often stays in her bed, but if she's really active she'll end up with one parent whilst the other gets in her bed. Difficult with twins, but it's a phase and there's little reward in waking up when everyone else is fast asleep.
When it started, she would chat and sing, want to go downstairs, ask for food - easy to give in to just to get it over with and get back to sleep. Now, all she is offered is a sip of water and any requests to play are ignored. Seems to be gradually working,
