It’s so difficult to follow the ups and
downs of a 2-year-old.One moment he’s beaming and friendly; the next he’s sullen
(愠怒的) and weepy, often for no apparent reason. These mood swings, however, are
just part of growing up. They are signs of the emotional changes taking place as
your child struggles to take control of actions, impulses, feelings and his
body. At this age, your child wants to explore the world and seek adventure. As a result, he’ll spend most of his time testing limits, his own, yours and his environment’s. Unfortunately, he still lacks many of the skills required for the safe accomplishment of everything he needs to do, and he often will need you to protect him. When he oversteps a limit and is pulled back, he often reacts with anger and frustration, possibly with a temper tantrum (发脾气) or sullen rage.
