This morning while I was playing with Paulchen, he said, "What you doing Cat?" I looked around me or a book with a picture of a cat and couldn't find anything. Then I realized he was probably calling me by my nickname. I asked him what he said and he repeated it. I had a good laugh and gently changed it to Mummy. Then he said it properly.
I went to tell Paul what his son said and ask him if he set me up. Paul was clueless and thought it was funny. Then Paulchen came in and looked at his father. I crossed my fingers that he would say "What you doing Paul?" What he said made me burst out and laugh. "What you doing Tiger?" Paul was shocked. He swore I told our son to say that, but I didn't. He used his Da's nickname. It was hilarious.
