Again, the energy behind the Rider is that of arrival, something new sweeping into a situation. This can be a person, a piece of news that the Rider delivers, a visitor who appears. The Rider is a herald of the new. For that reason, in this context, a Rider appearing in a reading simply suggests the appearance of something or someone new in the Querent’s life, whether that’s a new lover, a new friend, a new job, or just a new circumstance, depending on the context
The Child, if it’s not referring to an actual child or young person in a reading, can also represent new beginnings, the sense of starting off a new road. It’s not really just change or “something new” per se. The energy behind the Child card is specifically to do with a lack of experience, trying something brand new, a sense of innocence and brand newness, an endeavour never undertaken before. If it’s not about a literal child, it’s about someone starting off as if they were a child. Hence why the card can also represent beginners as well as children and the young.
The Stork, on the other hand, is about new beginnings in the sense of making changes in life, and is focused on this change-making aspect rather than any lack of experience indicated by the Child. This is about new starts, new beginnings, changing things, creating things anew. Making a fresh start, reviving something, perhaps.
