My sister bought us one, and my son could only use for 3 months. He started sitting up in it and trying to look over the sides. It really wasn't a life saver. If you find one cheap, buy it but don't pay full price not really wroth it in the long run
I just got one and it works with my daughter but it supposed to be used for my son when he comes. But it works wonders.. i would look on resale sites thats where i found mine
