It's no secret that Prince William and Kate Middleton will be the future King and Queen of England. What their plans are once they have those roles -- now that's a different story. However, based on what Kate has been up to, she'll more than be prepared for the job.

As Queen, Kate will champion different causes, and it seems she's found that at least one of her causes will involve children.

"She has found work that she’s really passionate about," a source told Hello. "She spent a lot of time at the start of her royal life learning about social issues and challenges like addiction, homelessness, mental health. It became clear to her that one of the main causes of it all was things not going right in the early years, so she knows the potential advantages to doing things in this space. It’s about solving much bigger problems but doing it early."

The source added, "She has spent a lot of time with a lot of experts and professionals and has learned from them. She has also done an enormous amount of reading on her own."

In addition to championing causes, the Duchess of Cambridge has taken on more royal duties in an effort to make the coming transition smoother.

As previously reported, as Kate has become more knowledgeable of royal protocol, she has attended more engagements and gone to more events solo, without her husband, Prince William, by her side.

The mother of three hasn't been on her own through this journey, though. A source revealed that Queen Elizabeth has "really taken Kate under her wing" and they will "often spend hours discussing royal life and the future of the monarchy," which will undoubtedly prove to be useful in the future.
