Wikipedia:Articles for deletion/Child of the Duke and Duchess of Cambridge
I have no idea how  would apply in this case--this child is the eldest child of the eldest child of the eldest child of the most famous monarch in the world. Regardless of gender, this child will in all likelyhood be the future monarch of the United Kingdom and even if the monarchy fails, a pretender. This is not the child of Tom Cruise, but a member of a royal family. Their notability derives from their birth into that family. We have an article for Princess Athena of Denmark despite the remote chance of her ever ascending the Danish throne, because as a member of royal family, she is inherently notable. I would even go as far to say that this article isn't specifically about the child, but about the circumstances around the pregnancy and the child's impending birth. At any rate, he or she will be born within the next couple weeks, maybe even before this AfD is closed
