We bought this product after using one of friends and we are very happy. Our baby (very tonic) 4 months has fun like crazy inside. Product very secure, no risk that the buoy turns. Attention on amazon title says 0-1 year but when you receive it on the box it is written 6 - 12 months. I think you have that baby can sit with assistance before tempt to put in and a baby small risk may be to regain a little lost in this big buoy ....?
