“In addition to being safe, toys for young children need to match their stages of development and emerging abilities. Many safe and appropriate play materials are free items typically found at home. Cardboard boxes, plastic bowls and lids, collections of plastic bottle caps, and other “treasures” can be used in more than one way by children of different ages. As you read the following lists of suggested toys for children of different ages, keep in mind that each child develops at an individual pace. Items on one list—as long as they are safe—can be good choices for children who are younger and older than the suggested age range.”
King Agesilaus was excessively fond of his children. Once when they were very small, he bestrode a stick, and was playing horse with them in the house, and when he was spied doing this by one of his friends, he entreated him not to tell anyone until he himself should be a father of children.
Plutarch, 46–120 AD
