I'm still in the "it depends" denial, but I grew up in a different era, where there was only something on TV for a few hours a day. Half an hour or 45 minutes of stuff aimed at kids at 3 age cohorts, toddler stuff, Sesame Street, "youth news", and an educational / entertainment / sketch show called Klokhuis (apple core / clock house).

But that was once a day, during weekdays, and no re-runs. Watching and re-watching Sesame Street clips back to back is IMO just as brainrotty to kids as the other brainrot going on at the moment.
