Our 3 year old has refused to sleep in her converted crib (now a toddler bed) for 3 weeks (at least) now. She sleeps on the floor, on a blanket that we laid down for her. She seems happy enough but it's so strange, why sleep on the floor?? She slept in her toddler bed for some time before deciding the floor was better. We're not ready to buy a "big girl" bed yet. She still fits in it, if she would sleep in it...
