In the video, the father was kind of suggesting and asking the children to leave the toys. Then he proceeded to tell them that they needed to leave those toys but they would get something else. He told them they could pick something out from the front and that their grandma would buy them something. He shouldn’t have told them that they would get toys later, he also shouldn’t have called the little girl a baby. That was inappropriate and unnecessary, that didn’t make the situation any better.
The father went wrong when he told the children they would get something else from the store, he just rewarded the children for throwing tantrums at the store. The dad needs to be more firm and demanding, he should tell them that they will leave those toys and walk away. I think that if the father would have been more firm and demanding the children wouldn’t have been throwing tantrums like that. Additionally, the dad could have ignored the behavior, or removed the children from the store so they could sit
