The tiniest mouse ever!

I was cooking boiled eggs for breakfast when just by chance I noticed this teeny weeny baby mouse hiding in the sink! Goodness knows how it got there, and I very much doubt it could survive by itself, but anyway. 
I put it under the hedge and left it to its own devices, what else could I do? I wasn’t going to hand rear it!
Later we took the children to the boating lake, then after lunch went swimming, where one of the children managed to cut his chin open! 
Never a dull moment!
