We are the proud owners of the original Bumbo chair, not the newer one with the silly seat belt. Sorry I feel like that seat belt is a total cop out. The original seat was clearly made for children to sit in on the floor and if you did choose to sit your child on a raised surface it was your responsibility as a parent to watch them. I do feel quite bad that there were some bad parenting moments where some children were injured in these seats. But I do not feel that adding the unnecessary seat belt (the seat is already snug enough) really is saving these children from inattentive parents. If they fall now the chair is just going to fall with/on them.
But let me step down from my soap box and give you my quick GENIUS moment. Mister loves his Bumbo seat, with or without the tray, but he is constantly dropping his toys on the ground (still working on using those little hands properly). But just add one of these clips to any toy and viola, instant toy catcher/holder!
