One thing we loved were these mesh bags that you put soft fruits and veggies in and they chew on the food through the mesh bag, it helps them learn to chew without the danger of choking, they can be a pain to clean but they work great.
this is what one step ahead sells,
) you can find them at babies 'r' us for cheaper. They have other brands there as well that are colors so the bananas don't stain as much. I may even have a few left over that didn't get used. If I find them I will let you know if you want them.
