This is how we try to keep our floors somewhat clean. We put a baking sheet under his highchair, where the majority of his food lands. What can't be helped is the food that he intentionally tosses off the side. Oh and incase you are wondering, our high chair came from IKEA and we love it. Affordable, simple, light weight...and I've heard other people say that they love it too. I would definitely recommend it to anyone who is shopping for a highchair.
