Toys I can make at home For Infants and Toddlers.?

I am in a early child development class and I have to make 3 toys. one for an Infant, one for a 1 yr old and one for a two year old. does anyone have any suggestions?? I am tight with money right now (Christmas) and need inexpensive toys to make at home. please help me with ideas and materials needed. thanks so much..

Stuffed animal or mobile for the Infant. You will need some material, needle and thread or sewing machine, stuffing, string or ribbon and a circular piece of plastic. All should be found easily at Wal-Mart or a craft store for cheap.
For the one year old I would do painted blocks. Cheap and fairly easy. Just have someone cut some wood into blocks and paint them with numbers or animals.
For the two year old I would make a picture book by hand (if you can’t draw you could use pictures from a coloring book and create the story yourself) or a homemade puzzle. That would be easiest, just take a piece of cardboard, draw a picture on it and cut it up.
