Trying to reason with or punish your child may actually make the tantrum last longer. It is best to make sure your toddler is in a safe place and then ignore the tantrum.

Toddlers are very curious and want to be the boss.
This is normal. If they are safe, this is a time to let your child explore new things. As long as you are there to protect your child, let him satisfy his curiosity. Stuffed animals, toys for pounding, pots, pans, measuring cups, empty boxes, and Nerf balls are some examples of toys your child may enjoy. Toddlers may want to imitate what you are doing.
