"Energetic" and "imaginative" best describe the 4-year-old. Often impatient and silly, they discover humor and spend a great deal of time being silly and telling you "jokes." A 4-year-old's language may range from silly words such as "batty-watty" to profanity. Loud, boisterous laughter may accompany such language.
Imagination suddenly becomes greater than life for the 4-year-old, who often confuses reality and "make-believe." Wild stories and exaggerations are common.
Four-year-olds feel good about the things they can do, show self-confidence, and are willing to try new adventures. They race up and down stairs or around corners, dash on tricycles or scooters, and pull wagons at full tilt. You still need to watch them closely as they cannot estimate their own abilities accurately and are capable of trying some outlandish and dangerous tricks.
