Continuity mistake: When CC and Maxwell arrive at the wedding, CC has no scarf around her neck. When the scene cuts to her shortly after arriving there is a large brightly-coloured scarf around her neck, and two shots later it has disappeared again.
Continuity mistake: In the dining room, CC is wearing a scarf over her head as part of her "safari" outfit. When the shot shifts to a close-up of her looking horrified at the thought of taking the kids to the Zoo on her own, the scarf is suddenly around her neck.
Answer: Children's brains and language skills are still developing at that age and they adapt to the environment they live in. My former boss was born in England and moved to the US at about eight years old. She completely lost her British accent by her teens, even though her parents still spoke as typical English citizens. A Japanese co-worker and his wife, also Japanese, spoke English as their second language. Their two children learned both English and Japanese simultaneously while growing up and spoke each language with the appropriate accent.
