NIKON D3100 MOde Troubleshoot?

My Nikon D3100 does not recognize the different scenes, for example, when I place it on "Child" the camera recognize "A" and not "Child". Please help.

Sounds like an internal electronic problem of the camera to me. Start the repair process with Nikon.

I still have to wonder why someone would buy a fully adjustable camera and then treat it as a P&S camera

Yes, there are a bunch of preprogrammed modes, but if you read your user manual, it will show the limits of the programmed modes. Most limits have to do with the quantity of light and the lens you are attempting to use.

If you want to shoot at shutter speeds high enough to capture "children" running around like maniacs, set your shutter speed to 1/500th second and let the camera pick the lens aperture (this is called shutter speed priority shooting). If instead, you are shooting portraits of a "child", the set your lens aperture to about f/8 and let the camera pick the shutter speed. This is known as using the aperture priority mode.

You have an excellent, fully adjustable camera. Learn now to use it without depending upon any preprogrammed modes and in the process learn the fundamentals of photography

Your camera has 5 Shooting Modes - P, S, A, M, and Auto. The others are called Scene Modes with the addition of the Guide Mode which is supposed to teach beginners. Those Scene modes actually use any of the 5 modes (except for M perhaps) in a more programmed manner. Scene Modes, most agree are junk and they usually don't work the way they should. I wonder why dSLR makers even bother putting them there.

Another way to shoot a moving child is to choose A mode. Set to lowest f/number. Set ISO to 800. This way you are assured of getting the fastest shutter speed possible for most decent lighting conditions. If shooting indoors or at night, you would be better off using flash at lowest possible ISO.
