"I just dropped George off, and he didn't want to go," the royal told another parent at Thomas's Battersea School during a visit to Milton Keynes on Tuesday for the town's 50th anniversary, People reported.

Prince William has been tasked with taking his son to school while Duchess Kate suffers from Hyperemesis gravidarum, a severe form of morning sickness, as she did with her two previous pregnancies. On Prince George's first day of school earlier this month, his father predicted the day would quickly come when the little royal was no longer excited to spend time in the classroom.

“We are all seeing how long that lasts before he doesn’t want to go,” he joked at the time. And it didn’t take long.
