There have been several people asking if certain places have bed rails for small children. Most don't. BUT...yesterday while online shopping (i know...i know...it has to stop) I found that one-step-ahead has inflatable bed rails that you position under the fitted sheet for any size bed. They come in a really small package with a plastic pump for $39.95. They get 5 out of 5 stars on 37 reviews. We haven't gotten ours yet but they seem like the perfect option for us. They are called "stay-put inflatable bed rail set". The website is onestepahead . com Just thought I would put that out there for those who have been looking/asking.
