Popsicles Anyone?

I just purchased this mesh Popsicle like thing for Leon. I saw a father on a playground in Boston with it. Basically you stuff the mesh pouch with food (I mixed banana and sweet potato in this one) and the baby can chew and suck on it. This way Leon gets all the "juice" out chocking on any big pieces. The only down fall was it's hard to clean. I tried cleaning it by hand first. Then I put it in the dishwasher. Even still it had food stuck in it.
