The DSes were out with DH this morning, and DS1 refused to let DH buy a Nestle product. He said, Mummy hates that company. Why? Because they want to stop milk boob and is mum stopped milk boob then DS2 would die. (DS2 is 23 months, and would be fine! But I'm sure he wouldn't think so.)
I'm not sure I've explained "unfair marketing practices to him very effectively, somehow" ...
