Character mistake: In the scene where Debbie is sitting in Dr. Pellegrino's office, she finds out she is pregnant. Dr. Pellegrino's name is spelled Pellagrino on his white medical jacket and Pellegrino on his desk.
Continuity mistake: In the scene when Debbie has lunch with her father in the restaurant, he shows her pictures of his other children on his iPhone. However when he shows her the phone it is upside down with the charger port facing up. Soon after when Debbie's father goes to the bathroom the Iphone is still upside down, now facing Debbie. In the next shot the phone is reside up with the charger port opposite to her.
Continuity mistake: In one scene, the family is watching SpongeBob SquarePants. However, the first time the TV is shown, one episode is playing. The next time the TV is shown, a different episode is playing (with a time difference between the episodes that doesn't make sense). The episodes involved are "That's No Lady" and "No Weenies Allowed", but I don't remember which order they come in.
Continuity mistake: When the kids are singing in the car, the leather behind them is white. The exterior shows the family's black BMW. In an earlier scene, the couple are driving to their romantic getaway in the same car, and the interior is black.
