Prince William and Duchess Catherine have banned their children from using iPads.
The royal couple don't want Prince George, four, and Princess Charlotte, two, to become reliant on technology for entertainment and want to encourage them to use their imaginations.
A source told Us Weekly: "They're very much seen as Mummy and Daddy's toys, not for children. As two people who grew up without gadgets for entertainment themselves, William and Kate are firm believers in toys, outdoor play, and encouraging an active imagination. They're very much a normal family."
Catherine, 35, recently spoke of her joy at seeing her children fall in love with nature.
The royal made reference to her kids in a speech she gave to mark the reopening of Hintze Hall at the Natural History Museum in London.
During her speech, the Duchess explained: "Like many of you here tonight, I remember visiting the Natural History Museum as a child, and being inspired with a love of nature.
"And now, as a parent myself, I am experiencing the joy all over again with my own children, who adore coming here, and it is not just to see the T-Rex mind you.
"Who could fail to be inspired standing here in this wonderful hall."
Meanwhile, William, 35, recently revealed to England women's soccer star Casey Stoney that George does not enjoy playing physical sports.
After a meeting with the future King, Casey shared: "[William] said at the moment he's trying to teach George that football is actually a contact sport.
"But George doesn't really like it when he's palming him off and getting physical."
Despite this, Prince William is apparently determined to improve his son's soccer skills, while he is also eager for two-year-old Princess Charlotte to develop an interest in sports.
Casey explained: "He said he's really encouraging his kids to get involved with sport."
