Imagine your child is twenty-five years old. Do you want your child to be able to say, “No, that’s not okay with me,” when someone asks her an inappropriate question? Do you want her to be able to ask for a raise? To be able to tell her partner, “I need you to talk to me more respectfully”? If we want our kids to be able to recognize their wants and needs as adults, then we need to start seeing tantrums as an essential part of their development.
