Mama is Fighting Everyday

I was looking around on the Japanese McDonald's site for "authentic teaching materials" and came across this page in the "Mama Station" section. You can even download an image file to print out your own t-shirt with the slogan "Mama is Fighting Everyday." The ad copy also refers to children as "little monsters". I mean they are sometimes, but does the concept of McDonald's referring to children as monsters really make Japanese mothers feel like the corporation feels their pain? Sometimes I wonder if raising kids in Japan is really that difficult or if a lot of mothers are just way too uptight about everything.
