And the Duchess of Cambridge was forced to miss taking son Prince George to school, after suffering from severe morning sickness.
But it seems the pregnant – who recently showed off her growing baby bump – has overcome the hyperemesis gravidarum, and is now arranging official royal engagements around his school times.
Speaking at the Place2Be School Leaders Forum, in London, the 35 year old opened up about how much she has learnt since the four year old started at St Thomas’s, in Battersea.
“As a mother just getting used to leaving my own child at the school gates, it is clear to me that it takes a whole community to help raise a child,” she explained.
“Whether we are school leaders, teachers, support staff or parents – we’re all in this together.
“We are all working to give children the emotional strength they need to face their futures and thrive.”

It was revealed she is pregnant with her third child back on September 4, with officials releasing a statement which read: “Their Royal Highnesses The Duke and Duchess of Cambridge are very pleased to announce that The Duchess of Cambridge is expecting their child.
“The Queen and members of both families are delighted with the news.
“As with their previous two pregnancies, The Duchess is suffering from Hyperemesis Gravidarum. Her Royal Highness will no longer carry out her planned engagement at the Hornsey Road Children’s Centre in London today.”
Kate was forced to miss out on George’s first day at school, with Prince William dropping the little one off alone.
The dad of two recently joked the youngster isn’t that fond of going into school as he had been on his first day.
During a visit to Milton Keynes, Prince Harry’s brother told a fellow parent: “I just dropped George off and he didn’t want to go.”
