I find this comment and in fact the whole discussion here racist! It is just because that this is an Indian channel, people are bashing it!
It has songs like this (https://www.youtube.com/watch?v=hq3yfQnllfQ&t=140s) with a billion views! This means millions of kids are learning their first alphabets. My kid learnt her rhymes from this channel.
It is completely upto us parents as to how much screen time they get. My kid gets 40 mins everyday and no more. I decide what to watch and I watch with them.
