Jeff Winckler, Educator, Father, says:

Around the age of two, tantrums are more common in many children. This is typically because children become frustrated in their inability to communicate their wants and needs...or because they don't get what they want! They are ready to talk to you but can't process or contextualize or rationalize everything around them. But that doesn't make it any easier you.

It's important to try and explain what's going on or "why" to a tantrunimg child. It's not too early to time a child out or have them sit in a spot (not too long) until they say "sorry" or make a better choice. It's also OK to take away privileges.
