I took LO to Target and sat her in the cart (which I wiped down as much as possible) and she kept sticking her little fingers in the holes of the cart and then putting her hand in her mouth--blech...!
All I kept thinking was that "this is how baby's get sick." Add this to my friends baby catching roseola at their pediatricians office and my OCD is going into overdrive.

How do you keep your baby's hands clean when you're out in public?
Since she still sucks on her fingers, I don't like to use anything with chemicals, even though wipes would be the easiest thing to use. Any tips or suggestions from veteran moms?
