Curly - My DS only used it for day naps, and as I said in one of my posts above he used it until he was almost two, then he just transitioned into his toddler bed with no issues. My sister transitioned her DS over at 6 months without any issues either. I know of others who haven't had a problem either, you just do it when you know your child is ready.

I feel like I should be a baby hammock sales person LOL!
