OK, just want to stalk this thread as DD is almost two and can climb on top of the cot rails. She hasn't actually fallen out yet but she could. I just bribe her to get back in with the threat of not reading her a story at the moment.

But I think the bed rails we have are only half-length so I'm a bit reluctant to transition her because I reckon she'll just scoot to the end of the bed and then get out.

Think I just have to take the plunge though!
