Continuity: There's a scene that opens with Carrie and her boyfriend in his apartment, and he's sitting with baby Brady on his lap. The camera cuts to another angle, and it's very obviously a different baby.

Continuity: When Carrie and Charlotte are at the park, Carrie has a black and white cookie that keeps changing position in her hands with each shot of her. First the chocolate side close to her, then away, then close again, etc.
