Our 2.5yo has different bed issues - basically she hates bed and starts screaming at the mere mention of it at night - and for us, we have to talk her into bedtime until she changes her mind so she goes voluntarily or she simply Will Not Sleep. She fills the bed up with soft toys, books, special blanket, night lights, hard toys, the works, and has to have a wind-up music thing on. And we *have* to make her bed into a cubbyhouse. She's fine with this, despite it not leaving much room for her in there

She's still in a cot for obvious reasons (which she *can* get out of but usually doesn't - its a long way down), and her door is one of few in the house that is toddler proof. This is by design, not accident.

I've never co-slept with her beyond the first week, she's a horrible sleeper. I co-slept with the other one for a few years on and off but I had no husband/partner so it didn't cause issues ... and she was the kind of baby who'd sleep through a house burning down (true story) and was fine in her own bed. They're all different, you just need to try something different and follow through with any threats/promises consistently until you've got a new routine.
