A free thing to do as a family is to head to the library! Check out books and dvd's, enjoy story hour and my own personal fave....sift through the coupon exchange box! I am not sure if all libraries have these, but the Chippewa one in Beaver county does. Last year when I was on maternity leave, the girls and I would head there for an afternoon activity. They would play with the puppets and look for books, and I would sit and look through coupons! I found a ton of useful coupons there and also brought in ones I wouldn't be using.
Next time you are at the library check and see if they have one, or if they would consider having one! Can't hurt to ask!
