When my boys were 6 and 8, Jean and I took them to Disneyland. That day, they were tired, wanted their own way, and had meltdowns. My solution was to say, “Control yourself, or you will never come here again.”
It was a silly parenting strategy on my part because Jean and I enjoyed going to Disneyland as much as the boys did. Which means I would have never followed through on the consequences I threatened.
