Yup. I have kids (three under 10), and the only time my kids use my phone is when I'm literally there with them, letting them pick a video (usually Pat and Mat, Bert and Ernie, or similar). It's not every day, and never more than 30 min, usually like 15-20 min, and we take turns picking.
I'm not letting my kids have their own phone until I trust them with one, and that doesn't seem to be happening anytime soon with how many of our other rules they break.
