I was baby sitting the other night and they were watching Dora the Explorer. When Dora asked the kids to count along with her they asked if I could say the numbers with them and teach them how to pronounce them. It was fun to teach them how to count to ten in spanish because it showed them that I really did know spanish number but it also is fun to go back to their house to baby sit and hear that they sometimes count things in spanish for their mom (even if they don't know all the numbers).
