Watching season 3 and 4 of LHOTP I was surprised to see Anna in season 3 "The Music Box" and Caroline Ingalls as a child in season 4 "I Remember, I Remember" played by the same actress, Katy Krutzman. Two completely different rolls, and she owned each one.

In "The Music Box" she plays Anna who stutters and so is picked on. She did a fantastic job playing that role, very meek and mild, half withdrawn.

Then in season 4 Katy returns to play the role of Caroline Ingalls as a child in "I Remember, I Remember" and goes completely opposite her role as Anna. Now she is smart and wise, sure of herself, and knows what she wants, Charles, lol. She plays the role to perfection and should have gotten an award for her looks of exasperation each time Charles failed to ask her out.

I didn't know it was the same girl and was impressed that she could pull off two completely different roles so well.
