If you leave the room, tell Baby you will be back. Give him some extra cuddling during these bursts of independence. First Teachers Researchers have found two styles of play between parents and their children . The professorial style is like having a conversation with a person who talks, but doesn't want you to talk. As you have probably guessed, the professorial style is not a very effective way of helping Baby learn.
Children seem to be able to learn more when their parents use a ping pong style.
When a parent does something, the child reacts to what the parent did. Another way this works is for the parent to react to what Baby does. If Baby giggles, mom giggles. If Baby hands a block to Dad, Dad hands two blocks back. Baby can stand, but may not know how to get down.
