Games : Does Mojang treat home family use of an account as a EULA violation?

The Minecraft EULA states under "Using our Game" section that

[...] you cannot sell or rent the Game, or make it available for access to other people [...]

However, I'd like to purchase the Game to play myself a little and to allow my kid to play as a reward for his school study success. Only one of us is expected to play the Game at any moment.

I am not asking for a lawyer advice. What I actually want to know is what the practice being implemented so far is: Have Mojang been enforcing one-license-per-family-member?
