We have a twin on the floor next to our bed that I end up in almost every night with the baby. She won't sleep in a baby bed, and at 13 mos still nurses at least once a night. She doesn't like dh in the bed with us, so putting her in our bed isn't comfortable. This seemed like the best option. It isn't as comfortable as my bed, but I sleep fine in it.
It folds up really small, so is easy to take with you. We just got back from 7 nights in WDW, and we took it with us in our checked luggage. I slept in it with the baby some nights, and ds12 used it others.
