Debbie's hack is sure to make us all slap our foreheads and wonder why we never came up with this ourselves:
Our one year-old daughter eats in a clip-on chair attached to our kitchen island. We put a large plastic "underbed" storage box under her chair to catch what she drops. Instead of sweeping or having to scrub a splat mat, we pick up the whole thing, carry it to the sink and give it a rinse with hot water. It's fast and I don't have to worry that she's picking up scraps that I haven't quite gotten to yet.
