The likes on Prince William and Kate Middleton’s Instagram photos are barely over a million.

However, when the royal couple posts images of their children on social media, they receive a massive response.

Princess Charlotte’s seventh birthday was recently honoured by the Duke and Duchess of Cambridge.

Before Charlotte’s birthday, her mother uploaded a number of photos of her daughter on Instagram. More than one million people loved the picture.

When the couple published more photos the next day, half a million more people reacted.
