The Terrible Twos

Joey Altobelli

The Terrible Twos are often characterized by oppositional behavior, mood changes, and temper tantrums. "No" becomes a favorite word. All are considered normal parts of child development, say the authors of "What to Expect: The Toddler Years." This is in part due to the fact that a toddler's ability to communicate hasn't caught up with his desire to communicate, hence his frustration and challenging behavior.

In some circles the Terrible Twos are also known as Joey Altobelli.
