Family Ties - Andrew. In one of the later seasons of the show, the mom had a new baby. The next show or season the new kid was like 6 years old, yet no one else had aged at all. I didn't even question it at the time.
Little House on the Prairie - Laura Ingles: School Marm. I used to occasionally watch this show when I was a kid. Now, I occassionally catch a glimpse of it on the Hallmark Channel. It appears that Laura grew up, got married, and became the school teacher while all of her school mates stayed as children and stayed in school. Laura became their school teacher.
