DD is 20 mo will soon be moving into the twin bed in her "big girl" room. The bed will have one side against the wall but due to the bed frame and the baseboard heat, it won't be flush against the wall. The gap isn't huge but there is a gap. Would you put a rail on each side? She is a big toss and turner and is often sleeping against the rails in her crib as it is.

Here is the rail I'm considering. If anyone has a different recommendation, I'd be happy to hear it!
