Of course, once a child is in a tantrum, there is really no helping. Toddlers act out in other ways as well. They can almost seem like scientists—experimenting with what is possible. If I throw this half-eaten cauliflower stem at Mom and say, “I don’t LIKE IT!,” what will happen? If I hit my sister on the head with a book, will she hit back? Will an adult stop me? The constant experimentation can be exhausting and confusing, especially as your kid gets to the point where it is harder to physically restrain them.
