If the royal baby had been born in another country or culture, he may have wound up with his head shaved, spat upon or have had his placenta buried.
GlobalPost looks far and wide for some fascinating birth customs from around the world.
1) The Netherlands
If the royal baby had been born in the Netherlands, his visitors would be treated to "beschuit met muisjes," which translates literally to "biscuits with little mice."
Don't worry, this is a Dutch tradition that does not involve little mice. Instead it is a delicious toasted pastry with sugar-coated anise seeds on top. Traditionally, if the baby is a boy, the seeds are white and blue, while a baby girl gets pink and white. When visitors come they chow down.
2) Mayan culture
The royal baby doesn't know it, but he is secretly glad his mama isn't Mayan. If she were, she would likely have doused the little guy in freezing cold water, which is thought to calm heat rash and promote restful sleep.

It's looking like the royal baby is going to be a George or a Henry, but if he had been born in Germany, Will and Kate would have had to choose his name from a list of preapproved names issued by the office of vital statistics, the Standesamt.
If you want to name your baby something that is not on the list, you have to submit the name for approval and the office will assess it based on whether it indicates gender (Matti for a boy, for instance, was rejected) and whether it is thought to have a potentially adverse effect on the child's life. If your name is rejected, though, you'll have to pick another and each time you submit one, you pay.
4) Muslim cultures
In many Muslim cultures, on the seventh day of the baby's life his father should make a sacrifice of a sheep and then the baby's head should be shaved. The sacrifice is called "aqiqah," and usually consists of two sheeps for a boy and one sheep for a girl. After the sacrifice, the baby's head is shaved and then the weight of his hair in silver is given to charity.
5) The Navajo
On the Navajo reservation, parents throw a party the first time a baby laughs. It's considered a significant event in that it marks the child's transition from the spirit world to the physical world. Careful though, the person who made the baby laugh is responsible for throwing the party and footing the bill.

A new mom in China spends 30 days in confinement with her newborn. She is not allowed to leave her home and is expected to adhere to a whole bunch of rules that include not being allowed to eat raw fruit or take a shower. The rules are aimed at restoring balance to the new mother's body. Many modern Chinese women struggle with the custom, though millions reportedly submit to it willingly every year.
According to NPR:
"Sitting the month," or "zuo yuezi," is deeply embedded in Chinese culture. It was even mentioned in the 2,000-year-old "Book of Changes," or "I-ching."
