ParentLock: just an (not so) ordinary life

Sherlock and John raise their 9 year old son George Hamish-Watson Holmes solving cases and having family game night is what have become of these two, but either couldn't be happier. George was adopted 5 years ago when John and Sherlock had just married and he has fit right into this odd family. He is quite an intellectual boy, a few years ahead of his peers in his school but does not care to brag, and of course Sherlock had taught him the violin (sort of, he's not the best player but he tries so hard to exceed at it) His favorite thing to do is to fix thing just like john, he is always taking in stray birds and animals to mend them and has said on numerous occasions that he wants to be a Doctor when he is older. How does family live their not so ordinary lives and how does Sherlock and john raise there growing son and manage to solve cases without John having a heart attack? (Warning; this is my first time writing so please forgive me, also i may have a bit too much fluff as i enjoy that)
