In light of this article, http://www.msnbc.msn.com/id/41838546...and_parenting/, it made me wonder if I should start using my shopping cart cover with DD. I don't use it now unless the cart is outside and metal and too cold. I will probably use it in the summer since the carts will be hot and I don't want DD to get a burn. Do you use a cover? Why or Why not?
