you had a baby from a previous relationship where your boyfriend had left immediately since he didn’t want the responsibility..right now that baby was about 1, his amen was Oliver and you lived a flat above Sherlock you of-course seen Sherlock on the newspaper on the Telly, and basically everywhere you go as he was popular for his work so ofcourse somehow you got dragged into the cases with him and John

as of now you had to go down to Scotland Yard and Sherlock had went with you…unfortunately you didn’t have a babysitter so Oliver went with you in a chest carrier
