Ideal for messy self-feeders my 6mo and 3.5yo both use them.  I like that they are thin and move easily with the kids so they don't make eating more difficult.  A good value but the wrist elastic especially doesn't last forever.  Criss-cross the ties in back to fit the neck to younger babies (see picture). For really juicy stuff, use without a shirt or put one underneath because with lots of liquid it will seep through.  We have 6 for two kids - when they aren't too messy we rinse them in the sink with dish soap, otherwise throw them in the washing machine.
