YolanDa's Band Jam, dubbed ‘Jools Holland for kids’, will be headlining on Saturday, August 27.
Captain Barnacles and Kwazii will be performing during a special Octonauts ‘To Your Stations’ show, as the headline for Sunday, August 28.
Other children’s favourite characters are also in attendance, including Fireman Sam, viral sensation Baby Shark, and Glitch and Ubercorn – superheroes from Go Jetters.
Adventure activities and meet and greets will also take place throughout the weekend, so little ones will be entertained throughout.
This includes the Lidl Mudder Zone, which gives kids a taste of the Tough Mudder assault course.
They can also learn sports and skating basics with Southsea Skatepark Mini Wheelers and S4K Sports.
Kids karaoke will also be available, so festival performers of the future will get the chance to display their music talents.
More relaxed activities such as face painting, den building and colouring are also included.
