Yucky!

Tyler has finally decided that eating food off the floor is yucky. I used to rush to pick up dropped Cheerios or other snacks that Tyler dropped on the floor before he picked them up and ate them. Now when Tyler accidentally drops food he says "Yucky!", picks up the food, and hands it to me to throw away. Tyler also picks up random stuff from the floor (e.g. pine needles, stray threads), says "Yucky!", and hands them to me to throw away. Should I take this as a sign that I should vacuum more?
