I’m amused with my kids. They don’t understand a lot of Thai but they still don’t get bored watching cartoons that are in Thai. My daughter picks up a lot of words and can understand better but my son is just contented watching the without really understanding anything. I’m sure he just understands by the gestures and facial expressions.
There were also times when my HUbby would watch the Malaysian Channel and my kids still gets glued to the tv on the tv box even if the show is in Malay. Maybe they’re quite used to watching shows in different languages. As for me, I easily get bored if I don’t understand the language ( especially those without subtitles). Maybe my kids will soon pick up Malay and Thai words here and there through watching TV.
