Can't help but interested to see, we put DD1 on a mattress on the floor before putting her into her 'big girl bed' and we hadn't yet bought side rails, she fell out once the first night () but hasn't fallen out again since, DP doesn't want to buy them for her as she's going ok but i'm not sure.

At this stage i am just wait and see but hopefully if i need to buy them you girls will give me some wonderful ideas.
