wow thanks PacRaKMG, thats great to know

Did you just get a guard or anything for the side?
No, we just took the side rails off and for the first week I made sure she had something soft to land on, on the floor, in case she rolled out. But she didn't! And the best bit is if she does wake up during the night, she knows how to get to our room by herself - no more me getting out of bed!
