I've been letting Ds(4) use youtube for kids to keep him occupied. It's about the only thing that's sure to keep him busy. I try not to overuse it but even then he'll touch the screen sometimes and change the video. Can anyone suggest something better?
We use BBC Kids iplayer. It's basically Cbeebies but on iplayer. You can also save videos (for a certain period of time, like 7-14 days) to watch offline if you'll be traveling or something and don't have the internet. They can still change them, but obviously much less likely to hit on random stuff. There are also apps you can download that let you lock the screen. I'm not sure how you find them or if they work on all tablets, but you could have a look.
I thought YouTube kids was ok until recently and there are still a lot of very unsuitable channels on there - the Elsa / Spider-Man / joker dressing up people - some very inappropriate content that can crop up. I use amazon prime ap for ds.
Very inappropriate and scary content on that channel - eating poop from toilet seat, child pregnancy and termination, sexualisation of children. Very bizarre and can’t believe it’s allowed. In YT kids you can’t even report a video or block a channel either so it can pop up at any time if your child watches something related to Elsa or Spider-Man or whatever. There’s some sick and nasty people about.
I don't let my son near phone or tablet with internet on, but he's allowed certain apps I've set up through kids place app. I've also downloaded Netflix programs for offline use, equally useful if you're out and about.
