Another difference in Japan and other countries. Japanese people don't give a sheet about which mother giving milk to her baby and where. Nobody complains. In other countries, the US for example, people complains about a mother giving milk to her baby in a restaurant tell them to go to the bathroom to do it. A bathroom!!!. Unless you take your lunch box to the bathroom and eat. Traditionally, Japanese are very tolerant of nudity and seem to separate sexual objects from feeding a baby. It all changed after Americans came to the country and forced them to open the ports. Westerners thought it was barbaric. It's common in Japan for father bathing his daughters or brother and sister take bath together(see "grave of fireflies", credited as the best movie you'll never want see again.).
