Continuity mistake: The dog poop on the ground moves when the father first pulls his car into the garage.
Continuity mistake: Cleo's pregnancy. When she goes to the doctor, they tell her she's 3-4 months pregnant and her baby is due in June. So she goes to the doctor in December (also they have a Christmas tree in the house when she tells the senora). When they go to the hacienda for the holidays which is still December, her belly is huge like she's 7 months pregnant already. Further more when they go back to the city and all go to the movie theater, her pregnant belly is gone.
