Hey @userEEBuXHe8nS, I hope you're doing well.
The Quick Setting tile for Kids Home is still there. You may need to add it to your grid though. To do so, pull down your Quick Settings>Press menu>Press Button order>Scroll through the available quick settings and drag and drop it to your grid.
I've attached an image to show it's there. If you need more information, don't hesitate to ask, I am here for you.
I hope this helps, take care!
