Occasionally after a nightmare or when I was sick, when I was really little. By the time I was around 4 or so, my parents would let me make up a bed on their floor. Outgrew that within a couple of years. I did share a bed with my mom or grandma once in a while when on a family trip or when there were a bunch of houseguests....and now that I think about it, on a trip a few years ago, I shared a bed with every other female at least one night. It was me, my dad, my cousin, her husband, their daughter, the daughter's best friend, and my best friend in a two-bedroom condo with two queens and a sleeper sofa. We all sort of rotated around so everyone got a good night's sleep now and then.
