Prince William's mother, Princess Diana, died in a car crash when he was just 15.
The Prince lost his mother very young which might have affected his attitude towards parenthood and fear for his children.
In an interview he has confessed he worries that he won't get to see George and Charlotte grow up.
In a new documentary with Ant and Dec the Duke of Cambridge admitted that fatherhood has made him more 'emotional' and more aware of how 'precious life is'.
With Prince Harry by his side, William said how he is 'weirdly' worried about smallest things and get affected by all sorts of things.
He said, "Just because you realise how precious life is and it puts it all in perspective. The idea of not being around to see your children grow up and stuff like that."
Meanwhile, Prince Harry talked about how he enjoyed living next door to his brother and his family at Kensington Palace.
William, 33-year-old, who is employed with the East Anglian Air Ambulance, will now work from a new purpose-built air ambulance base at Cambridge Airport and it's hoped the office make-over will help the crew's performance.
Crew member Dr Neil Berry revealed: "Our job involves very intense 20 to 30-minute bursts of activity which can be very high pressure and demanding. In between it is vital for us to remain relaxed and focused so that we can help patients to the best of our ability."

Prince William - who is as an air ambulance rescue pilot for the Cambridgeshire, Norfolk, Suffolk and Bedfordshire areas of England - will enjoy the benefit of improved sleeping areas, kit storage and a toaster, which was not allowed in the previous building because of safety concerns.
But the royal - who works four days a week and donates all his salary to charity - will importantly have somewhere to 'decompress' after an incident, as the service regularly completes more than 150 missions each month.
He told The Telegraph newspaper: "It is also important that we can decompress after an incident and the new base has room for us to go off as a team, talk about it and try to understand what we've seen."
When Ant And Dec Met The Prince: 40 Years Of The Prince's Trust, will be screened on ITV on Monday.
