My friend from Noah's gymnastics class told me about these things. You put a piece of food in the mesh part and the baby can suck, chew, and drool all over it until the food is small enough to come through the mesh and then it's safe for them to eat. We tried it out for the first time the other day and Griffin LOVED it! It gave a me a few minutes unload and reload the dishwasher. Griffin is really clingy lately so, anything that keeps him occupied for a minute or two is very much appreciated!
