My niece can’t pronounce my name yet so she calls me Babi, which ironically also means grandma in my mother language.
When I was young we got these at the dentist. It was usually a bee for courage and bravery for the massacre going on in your mouth beforehand. I hated the dentist and the stamps actually helped a bit. Was bit surprised they get these now for potty training. I’m not too sold on the idea but next time I will be prepared. I’m stamping my whole hand when visiting. I alone will hold the potty master title!
And you can even get poo and toilet paper stamps now. The wonder of human evolution.
