Is there a way to lock the volume & brightness on iPad/iOS 10 from getting changed by a child? My little boy watches stuff on our iPad all the time, the smart monkey figured out how to change the volume and the brightness by pulling up the Control Center and adjusting them via the slider.

My problem is that he sets them to the maximum no matter how many times I tell him not to do that. Is there a way to lock them on a certain level? or disable the Control Center?

Edit: Sadly redeagle's solution never worked, I have no idea what is "Volume Limit" in the restrictions used for but my kid can still control the volume using the control centre and/or the side switch
For brightness, you can go in Settings > Control Center and change if you want access to Control Center on the lock screen or within apps, it will always be available on the home screen, AFAIK.

To prevent him from changing the volume, change the volume to what you always want it to be and go to Settings > General > Restrictions and tap Enable Restrictions, then set a Restrictions passcode (something different than the normal passcode). Go to Volume Limit and check Don't Allow Changes.
