In most languages the word for mother starts with M (usually it's the first sound a baby makes) except for Fijian where it's Nana, in Mongolia it's Ana and in Japanese it's Okaa-san. In Old Japanese it was Papa. In modern Japanese it's Mama but that is generally interpreted as meaning food.
Australia's first Mother’s Day was in 1924. It came from the Christian tradition of Mothering Sunday when the faithful would return to the "mother church" during Lent. This was gradually replaced in the 1930s and 1940s with the American Mother’s Day, created by Anna Jarvis in 1908. Later in life, she campaigned against the day's commercialisation and tried hard to have it removed from the calendar. Anna was never a mother herself.
The first wife of Feodor Vassilyev (name unknown) of Shuya, Russia, has the officially highest recorded number of children born to her: 69 children. Between 1725 and 1765 she had a total of 27 pregnancies, giving birth to 16 pairs of twins, seven sets of triplets, and four sets of quadruplets, 67 of whom survived infancy. That's a lot of homemade picture frames and fridge magnets on Mother's Day!
