Why did Princess Diana call William Wombat?

Princess Diana called Prince William "Wombat" affectionately when he was a two-year-old child after visiting Australia, where the wombat is a local animal. The nickname is believed to have originated during a royal tour of Australia and New Zealand that Prince Charles and Princess Diana undertook in 1983. The local wildlife, including wombats, likely made an impression on the young prince and his mother, leading to the creation of the nickname. Diana used the nickname in an affectionate and playful manner, and it stuck with Prince William throughout his life, even though he wasn’t particularly fond of it initially. It became a reminder of the special moments he shared with his mother and the unique bond they had.
