K.N.
I got two books from the library called the Very Busy Toddler Book or something like that it has 365 ideas of things you can do or your toddler can do with things you have around the house like pans, cotton balls, and water. These helped us immensely. There are also a couple of books called the Kids Book of Concoctions, it gives all kinds of things to play with like play doh made out of peanut butter I'm sure this can be found at the library too. My girls loved this stuff.
