Mustard or Ketchup?

So while at the store the other day with my mom and sister, I needed something to occupy Will in the cart while we shopped. to the rescue..........a plastic ketchup and mustard bottle set for $3. He played with it the whole time. And now that we are home, he is having a ball with these simple bottles. They were a huge hit in the bath tub too- fill them up, empty them, pour them into each other and of course, SQUIRT!
