I bought a bumbo seat second hand for my son, I find to buy new they are priced very high! I put my son in this at the recommended age and I never trusted him in it, it would sit him up, but he looked uncomfortable, when he would cry, he would stretch out, it looked like he would actually be able to fall out of the seat, I never trusted the seat, he never actually fell out because I was always close by but he could knock the tray off when he stretched out. I would recommend just buying a bouncy seat, cheaper and you can actually get a lot more use out of it!
