sherlock john gif

I love this because you can read his lips and look at his hand gestures and just know he’s saying “Oh look it’s daddy, hiiiiii!!” and who the fuck says that to anyone without using a patronising baby voice?!

So really; Sherlock is using a baby voice to try and teach Rosie works and hand signals so she responds well to him and isn’t that just some fine character dovelopment RIGHT there
