Set the session boundary in Settings
In the ABC Kids video app, open Settings and use Limit Screen Time to choose a session of up to sixty minutes. ABC says expiry locks further video playback until the pin pad is used. It also documents an automatic unlock two hours after the last elapsed timer, so the timer is a session control rather than an indefinite block on the application.
Choose how episodes continue
The separate Play Next setting starts another available episode of the same programme. Its thumbnail and countdown appear as the current episode ends; tapping the thumbnail starts the next one immediately. Turn Play Next off in Settings when you want that episode to end the viewing. This is different from filtering a show, which hides it from the home screen.
Use a playlist for a mixed selection
ABC’s playlist instructions describe episodes from different programmes with the total duration visible before playback. In the Apple-device workflow, open Playlists For You, select a playlist and choose Play all. The selection ends when the playlist finishes. That gives a carer a way to choose a finite mixed session instead of relying on ordinary same-show continuation.
Keep the casting limitation in the plan
The playlist help specifically says Chromecast does not work with these playlists and recommends an individual programme when casting. A normal episode reaching the television therefore does not prove the mixed-playlist function is supported there. Choose the intended route before the session: a finite playlist on the mobile screen or an individually selected programme for Chromecast.
