It is every father's wish to see their children grow up as this will be the time that their kids need them the most. But Prince William just recently revealed in a documentary by Anthony McPartlin and Declan Donnell that his greatest fear is that he will not witness Prince George and Princess Charlotte's growing years.

The 33-year-old Duke of Cambridge admitted that being a dad brought a lot of change in his life, including the way he acts and connects to the world.  "I'm a lot more emotional than I used to be. Yeah, weirdly," he told the ITV interview which will air on Jan. 4, according to Us Weekly.

"I never used to really get too wound up or worried about things but now the smallest little things can get — I can feel — you well up a little bit more." He also added that the thought of not seeing and guiding his little tots to become good men when they grow up frightens him.

"You get affected by things that happen around the world or whatever a lot more, I think, as a father, just because you realize 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," he said. To recall, Prince William and his younger brother Prince Harry's mother Princess Diana died when they were just little ones on Aug. 31, 1997.

However, the first wife of Prince Charles made a big influence on his sons' lives, the husband of Kate Middleton justified. Meanwhile, Yahoo! News added that the said documentary will mark the 40 years of The Prince's Trust, the charity built by the 67-year-old Prince of Wales himself.

The organization aims to help young people exempted from the society due to lack of opportunities. In 1976, the son of Elizabeth II used the £7,400 he got when he left the Royal Navy to finance different community projects.
