Continuity mistake: When Charlotte and Carrie are sitting at a table outside, there is a woman with a long brown leather coat walking by. Shortly afterwards the same woman with the long brown leather coat walks by again. (00:08:20)
Continuity mistake: Up until this time, the baby Brady has been shown to be larger, with a very round face and red hair. But when they show the baby in the crib (04:22) this is a different baby. It's much younger, smaller, no round face, and has dark brown hair. And later, when Steve's mother shows Miranda the photo of Brady, (14:21) again it's a much smaller, younger baby with dark brown hair, and no round face. During the actual Baptism, when they show close-ups of Carrie holding Brady while Charlotte takes pictures; (26:20) the baby looks like yet another baby that is smaller and younger, but appears to have reddish hair. Looks like they used 3 different babies to represent Brady at this point. (00:04:20 - 00:26:20)
Continuity mistake: Carrie enters the chapel with Miranda and says the godfather smells bad. Carrie places her arm around Miranda, but it disappears a shot later.
