It sounds like the Cambridge household is about to get a whole lot noisier after the Duke and Duchess of Cambridge were presented with brass whistles for Prince George and Princess Charlotte during a public engagement on Wednesday (22 November). Prince William appeared to imply that a rowdy George would probably end up making the most out of the gift.

The royal couple—who are currently expecting their third child—were in Birmingham in the United Kingdom for a series of engagements this week, which included a tour of Acme Whistles, where they were given a bag full of gifts.

Prince William joked that they’d never have peace again as soon as four-year-old George got his hands on the whistles, saying (via Hello!): “Don’t show that to George; we’ll never get any peace!”

The Duke and Duchess also visited Aston Villa Football Club—William is a well-known supporter of the team.

They also spoke with local children who were taking part in training sessions with Coach Core apprentices and tutors.

Kate appears to be recovering after suffering from severe morning sickness, and recently revealed she was well enough to take George on the school run. She admitted that it was still tough to leave George at the school gates, but that she was slowly getting used to it.
