Nadya Suleman, aka Octomom, had the most kids in one birth to survive. Her octuplets, six boys and two girls, were born in 2009. An Indian woman named Omkari Panwar became the world's oldest mother when she gave birth at age 72. 46% of Americans believe the ideal number of kids to have is two, yet the average number of people in a family is just over three. The cost of raising a child from birth to age 18 is around $233,610. In some countries, like Russia and Japan, it's considered bad luck to have a baby shower. Children don't really start remembering things until they're about seven. So your kid probably won't remember those terrible twos.
