If things ever get to be too much and I need to break the ice at home, one technique I employ is the Intentionally Missed High-Five.
I will grab any of the kids and make them perform an #IMHF with me or with each other if they are fighting.
It is nearly impossible not to break down laughing afterwards. Do not recommend trying to record in order to avoid tainting the moment. This could be an Olympic sport.
Good Luck. ❤️🤣
