The Consulting Babysitter

This is my first fanfic, so I hope you enjoy! I, of course, don't own Sherlock, but John's child, Hamish, is from my own imagination. The rest belongs to BBC. I started writing after The Sign of Three, so it doesn't quite match with His Last Vow, but I hope you like the result of Sherlock babysitting John and Mary's child. I also added minor Johnlock.
