I bought one when my son was 18 months old and I never used it (sold it on craigslist). My son was way too active to fall asleep in it. It was very easy to set up, take down, etc. but it was so relatively small and confining compared to a crib or pack-n-play that it was impossible for my son to fall asleep in it. It became more of a place to play than to sleep. Personally, I wouldn't recommend it for babies/kids over 1 yr.
