It's every parent's worst nightmare - trying to keep your grumpy preschooler in check with the eyes of the world upon you.
Thankfully, the Duchess of Cambridge rose to the challenge when her youngest son Louis, aged four, threw a wobbler at the lengthy weekend of celebrations for his great-grandmother's Platinum Jubilee.
The mischievous prince was seen putting his hand across his mum's mouth to shush her, sticking his tongue out and blowing a raspberry during the Platinum Party at the Palace concert.
A week on and we're still debating whether Louis should have behaved that way - and if Kate responded in the right fashion.
"A spoiled brat or a just a normal four-year-old?" asked the New York Post, while many posters on social media, of course, insisted their children would NEVER have behaved like that.

Well, my preschooler certainly would have and I think Kate did brilliantly.
