Before you know it, the somewhat calm child of three becomes a dynamo of energy, drive, bossiness, belligerence, and generally out-of-bounds behavior. You may be reminded of the earlier trials and tribulations you went through when he was two. Also obvious during this time is the tremendous spurt of imaginative ideas that spring from children’s minds and mouths. All of this behavior and thinking will help your youngster build a secure foundation as he emerges into the world of kindergarten.
