Thinking of moving DD to a toddler bed soon (well her cotbed converts so more taking the sides off). She's 2.5. It will be head-end against the wall if that makes sense, so both sides will be open. Toddler beds are fairly low to be floor and obviously she needs to learn to stay put at some point. Did you use bed guards for your little ones or just leave them to it in a toddler bed? She doesn't move too much in her sleep and I usually tuck the duvet down one side anyway.
