Coinciding with the start of the school summer holidays, dozens of popular children's shows such as SpongeBob SquarePants, Ben10 and iCarly can be watched on-demand via Sky Go on smartphones, tablets, laptops, PC and Mac.
Sky said that the service would help parents keep the kids entertained on long journeys to a family holiday, or if the UK is hit with another "summer downpour".
Video on-demand content from eight children's channels is available now on Sky Go, including Cartoon Network, the Disney Channel and Nickelodeon. The programming can be viewed at no extra cost by Sky TV customers with the Entertainment Extra pack.
Next month, eight live streams of the selected kids channels will be added to Sky Go, meaning their will be a total of 32 live channels available on the service, including entertainment, sport, news and movies.
"Arriving just in time for the beginning of the summer holidays, Sky Go now offers kids the chance to watch dozens of shows while out and about across a range of internet-connected mobile devices," said Holly Knill, the head of Sky Go.
"We'll be adding live channels later this summer too, giving kids more choice than ever over how, when and where they can enjoy their favourite programmes."
Sky Go, which launched last year following the merging of Sky Mobile TV and Sky Player, attracted 2.7 million unique users during the three months to the end of June, said Sky.
Also today, Sky has announced a forthcoming update to its Sky+ mobile app on the iPad, which will enable the firm's customers to use the Apple tablet as a remote control.
Launching later in the summer, the update means users can pause and rewind Sky TV by swiping their iPad screen.
Customers with Sky+ HD boxes can view their Sky Planner on the iPad app and then add or delete shows without interrupting what they are watching on the main screen.
