This toddler throws a tantrum from the smallest of reasons and shows the reality of parenting.

In the clip, filmed on May 1 in Phoenix, Arizona, the toddler can be seen throwing a tennis ball up in the air.

As she collects the ball, she falls onto her backside and begins to cry.

"What's the matter?" asks her father.

"I fell over," the girl responds.

But her father isn't buying it.
