First thing we do when we get home? Ditch the shoes. Why? Because nothing spreads germs faster than walking them all over your house. And when I say "germs," what I really mean is fecal bacteria, mold, and even allergens. There have been numerous studies done on the bottom of your shoes, and the fact of the matter is, you never really know where you've been stepping on all day. And when you have a toddler or baby crawling around at home, it's better to be safe in socks than sorry in sneakers.
