While at the Newell family reunion Bryn learns to swim (his own way) and then gives Beth and Peter a taste of their own parenting medicine.  Back home Beth and Peter prepare for Bryn’s upcoming fourth birthday,  Peter has a contentious exchange with a cake designer about the existence of brown spotted cows, Beth shares a study that challenges the validity of parenting styles and a listener ‘Would You Knows?’ asks Peter and Beth to debates who gets the last two seats on an alien rescue ship.
