The preschool years are a time when bodies are expanding at a fast speed. Kids can do something new daily it seems. At preschool they can race with other children to find out exactly how rapid their bodies can go. Combine this with jumping, skipping, hopping, dancing, training and crawling. "Wow, I really did not understand I might do this", I have actually listened to youngsters say. They are examining out their buddies to see what they are doing also. Their physical skills will be challenged daily at preschool.
