1. A deck of sturdy, circular plastic cards, each about the size of an adult's palm, with photographs of everyday objects or African animals or body parts or other things you find in, say, Priddy books. If you must make them "educational," the reverse of each could have the word, or the initial of the word.
2. Board books made of sturdy plastic or wood, so that gnawing youngsters don't A) destroy them and B) end up with little pieces of semi-dissolved paper in their mouths.
3. A toy with one very easy to operate switch that turns a light on and off. Bonus if the switch is actually shaped like a real light switch.
4. Boxes with hinged lids and different kinds of closing mechanisms, all slightly challenging, in which parents can stow different assortments of interesting gummable and handleable objects.
If any of these things do exist, please tell me where to buy them.
