AIBU to shut down my five year old's poo chat and jokes? I know it's developmentally normal to find poo hilarious, but should I redirect him when he makes a "poo poo palace" out of bubbles in the bath or does butt water pistols on his bike (by standing up when pedalling and pointing his bum backwards - admittedly hilarious). I don't want to curtail his attempts at jokes but the poo theme seems a bit strong. Advice welcome!
