Hitting, back-talking, screaming fits, and the list goes on... Your child's second year can seem totally defiant and self-centered. But this is just a normal part of your toddler's emotional development where he is starting to test his independence. Here, experts explain why toddlerhood is filled with vexing episodes of unacceptable outbursts in public, temper tantrums and more.

Understanding the "terrible twos" phase

Kids at this age can really test your patience when things don't go exactly their way. Particularly when things don't go their way in the middle of a public place. Yes, like your child screaming at the top of his lungs when you refuse to buy him the candy at the supermarket.

This is known as a "temper tantrum" and here's the reason: At this age, your child is developing personal preferences, but he doesn't yet have the language skills to express what he wants. He also lacks the cognitive skills to understand why he can't always have his way. (Concepts like sharing, taking turns and waiting for something are beyond his grasp.) This is why he expresses himself with a loud no, a scream or even a temper tantrum.

The good news is, your child's tantrums will ease when he learns to express himself properly. Still, that's not to say that until he does, you should simply throw up your hands and give in. In fact, toddlerhood is an ideal time to start setting limits so your child learns that he can't always have his way. Whenever your child starts throwing a fit, experts advise it's important to stand your ground and be firm - if you give in to tantrums, you'll see more of them.
