Look, we totally get it.

School is important – and I am sure most of you, like me, have rules in place when it comes to what is and isn't allowed on a school night. And this is the same for royals, it would seem. The Duke and Duchess of Cambridge recently attended the Royal Variety Performance at the Palladium Theatre in London, an  annual performance held in aid of the Royal Variety Charity, of which Her Majesty The Queen is Patron. After the event, veteran British singer Petula Clark chatted to the Kate, who revealed just how strict she is when it comes to George and Charlotte's routines now that they are both in 'big school.' Clark later told reporters that the royal mum-of-three had clear views on school term routines, and that Kate had refused her two eldest children's requests to attend the concert along with their mum and dad. “As she chatted with Petula Clark the Duchess said her children had been really excited about where she and William were going – particularly the dancing and singing – and asked if they could come but she had to tell them ‘not on a school night’,” The Mirror reports. And sure look, we have all been around the block, we know how tricky it is to get over-tired kids into bed. Sounds like a good call, Kate!
