Revealing: In the episodes where Michelle is a toddler, during the opening you can see her point to the camera during the car/bridge part. Jesse tries to make it look cute by laughing and pushing her arm down.

Revealing: In almost every episode where Michelle is a toddler, you can always see her look to the right or left to most likely a person telling her what to do.

Continuity: On the first floor of the house, there are two staircases leading up to the second floor - from the kitchen and the living room. But on the second floor, there is only one staircase leading down. And it doesn't matter which one they use, they still end up coming upstairs in the same place.

Continuity: In later episodes, the door to the attic is located before the last set of stairs in the upstairs hallway. But in earlier episodes, there is no door; just a wall with a picture hanging.

Continuity: Whenever the door is opened, there is a small patio with plants, large enough to reasonably hold 5 standing people, however this patio doesn't exist in the opening credits.
