I’ve got my flameproof knickers on for this because I know, I’m being lazy allowing my child to use a phone to keep him quiet for a moment, but I really don’t want him using YouTube any more.
We tend to let him look at our phones for a few minutes to brush his teeth (he hates it so the couple of minutes playing with the phone usually buys us enough time). Last week I heard my partner saying “no, that’s not nice!” and our son crying because the phone had been taken off him. Turns out he had been watching one of those ubiquitous ‘Mummy Finger Daddy Finger’ videos and it had animals fighting each other in 
I was upset about it at the time and now there seems to be news all the time about apps and videos aimed at kids being something horrible instead (like the Blaze app that went viral). I want to stop him using YouTube altogether and only have access to “safe” stuff like CBeebies content.
My partner says I’m overreacting and he’s got all his settings such that our son won’t see anything harmful. But I don’t really want to take the risk.
