We've taken the sides off my 2.5 year old's cot bed (stupidly and prematurely). We have also given him a duvet and pillow. He's not getting on with it all at all. Considering going back to sleeping bag (which he loves) in toddler bed. Has anyone done this? He so far hasn't fallen out of bed or got up and wandered around in the morning. He can walk ok in the sleeping bag. Any thoughts? I would rather not spend this afternoon reattaching cod bed sides!
