I bumped into a really cool search engine that is specifically for kids , to avoid any unsuitable pop-ups . both of the search engines are the same they just have different outlook other than google , but add to it colorful fonts for kids and more friendlier for them.
Kiddle will be in much use as it provides images and videos search other than Kidrex that don’t.
as for videos , sometimes we can find a really good video for our kids but the suggestions for the other video are so unsuitable for their age , so you just run and make the video a full screen and try to hide is that the solution ?
there is a really handy web tool called quietube you just follow the instructions and it will hide all the video surroundings and distractions and leave it more quieter.
