Is this first season Stephanie or last season Michelle in Full House?

When most people picture the Tanner sisters from Full House, they probably see D.J. as a teenager, Steph in elementary school and little Michelle as a toddler. In fact, Candace Cameron (D.J.) was only 11 and Jodie Sweetin (Stephanie) was only 5 when the show started in 1987. And the beloved sitcom ran so long that the common practice of casting twin babies in the same role saw Mary-Kate and Ashley Olsen both play 8-year-old Michelle in the final season.

We’ve collected a few scenes from the early episodes featuring Stephanie and some from the last season with Michelle. Can you tell the difference between the middle and youngest Tanner sisters when they are around the same age?
