green sprouts Baby Food Jar Holder, Green

So, sometimes my child will NOT sit in his highchair and wants to be held when he eats. No problem, except I only have one free hand, then his food container will slide all over the counter as I try to scoop. I bought this item in hopes it would work, even though we don't use baby food jars. We make his food, but I found if you use these containers : GladWare Mini Round-8 ct they fit great!! I think this is a great product. It's also great practice for my child to feed himself while in his highchair, so the container won't slide all over the tray.
