I'm a 3D Character Animator.
Yes Blender is a good choice, although I dont use it but I need to start looking at it again since that now they totally revamped it with version 2.8 and for the better.
The Industry standard is Maya, especially for Character Animation, but by the time he grows up and want a job on it who knows what tool will still be relevant.
Also and even though its a dying "form" of communication... make him get used to forums like this:https://blenderartists.org/https://www.blendernation.com/https://forums.cgsociety.org/c/addit...ftware/blender
BLender changed a lot on this recent version (2.8) so he might be lost if trying to follow tutorials for older versions. Its a matter of time until the web will be filled with tutorials (free and paid) for the new version.
The source of knowledge forums have is immense and he can browse for even more knowledge if he needs and he will. 3D is so vast that initially he will start doing a bit of everything but sooner or later he will start to specialize, being on Modeling or Animation or Character Animation or VFX etc. Its a never ending learning process.
I would also advise to give him a proper PC. 14 " is just to small of a screen and he will get eyesight tired and he is too young for that. Protect him now and he will thank you later. Any cheap 20"-21" inch screen will be better to look at than a tiny Laptop one.
