In season 3 of Ghost Whisperer, the character Ned (Son of Melinda's co-worker Delia Banks, originally played by Tyler Patrick Jones was replaced by Christoph Sanders.
Given that there is a very large difference visually between the two (as well as an apparent jump in age of the character), was there a casting/out of universe reason for the change?
As stated in the Wikipedia page for Christoph Sanders:
He took over the role of Ned, which was previously held by Tyler Patrick Jones, when producers decided to age the character by few years in order to explore more mature storylines.
As the source for this, the page refers to the book Ghost Whisperer Spirit Guide by Kim Moses and Ian Sander (Titan Books, 2008).
