Query: Good concept, but doesn't work for my daughter.

I bought this placemat because the idea of a tray that catches the food appealed to me. However, the tray is extremely flexible. When I used this for my daughter, she would press her body against it, put her hands in it, or bend it and the food would get all over her clothes. This was especially a problem when she would eat messy foods such as applesauce or spaghetti.
