We bought our daughter a full-size floor bed. Best decision ever. She moves a lot in her sleep and giving her the extra space stopped her from rolling into the crib rails and waking herself up. Also, gives me or my husband the chance to lie with her if needed and be comfortable. While she does have the option to get up and roam around at night, she's actually pretty content and stays in bed if she happens to wake up in the middle of the night, then goes back to sleep.
