I have a policewoman at home and her name is Inez Low.
Every time when we get into the car and once she’s strapped up in her car seat, she will immediately say “Mummy, your seat belt” once I got into my seat. Usually Daddy will only strap his seat belt after he has started the engine and drive off the car. Inez will scream “Daddy, your seat belt, your seat belt.” She will keep repeating until she sees her Daddy strapped the seat belt, only then she will be satisfied and say “Good Job!”
