Baby squirrel

Found this squirrel Baby under a tree, it had fallen out of it's nest over 5 m high! We left it under the tree for half a day to see if the mother would fetch it but she didn't come, so we took it in when it got cold and dark.
It only had two injuries, a cut on it's mouth (which had a maggot in it yuk!!) and one on it's leg.
Well, it's pretty tough, the wounds have healed, it's been feeding and sleeping for three days and getting stronger....
