Prince William and Kate Middleton left someone behind on their trip to New York -- Prince George. The couple has reportedly opted to leave their one-year-old at home for the three-day trip, CNN reports.

Why would the royals leave the baby at home? Well, he’d probably be bored. The Duke and Duchess of Cambridge have jam-packed their short trip with charity events and appearances. They’ll even have to separate for a short period of time while William visits Washington, D.C. to meet President Obama. While exciting for those who follow the royals and those who could benefit from causes they support, the trip wouldn’t be too fun for Prince George. The packed schedule “doesn't make it appropriate to bring him,” a source told CNN.

Many may have expected Prince George after he attended William and Kate’s visit to Australia and New Zealand earlier this year. The Duke and Duchess brought him on their three-week trip down under, but the schedule was more suited to George’s needs. They made appearances at Taronga Zoo and scheduled play dates to accomodate the baby, but no kid-friendly arrangements were made for this trip to the U.S. Also, the longer trip may have been a factor. The new parents likely didn’t want to leave their nine-month-old at home for weeks. In comparison, three days isn't that long. 

Leaving the baby at home isn’t unheard of for the royal family. In fact, William was left at home when his parents visited the U.S. in 1985. Princess Diana and Prince Charles opted to leaved William, 3, and Harry, 1, home while they spent four days in Washington, D.C. and FLr
