My kids are unhinged on Yt Shorts

This is more of a rant but ngl the 15-second video thing is RUINING their attention spans. My 7yo will watch like 200 shorts in a row and I genuinely don't think his brain is processing any of it. It's just infinite dopamine hits. I blocked YouTube Shorts on his iPad and he literally looked at me like I killed his dog. Send help and/or validation that I'm doing the right thing.
