Little Wee Man goes to to the Zoo

Lovely day in Scotland visiting family & seeing the animals at the zoo. Jackson managed so well I’m very proud.
One of the photos I took highlights something that is concerning me.since he banged his head on the hearth (21st July) as he has had a blood shot left eye. I have had it checked by GP who says there is nothing to worry about but I think it is getting worse.

Has anyone had anything similar???
