Thanks, that works. However, now I have an issue with the array parameter 'number'. I want it to select the first 4 child pages based on 'page order' with an offset of 1.
But now I have to put 'number' => '16' to grab the first 4 pages in one language and 5 pages in English.
Any clue how to solve this issue?
