A little girl sits with her mother on a stone stool

A little girl sits on a stone stool with her mother beside her. This picture was presumably taken on a summer holiday along with the other photos in the series and at least one of those was taken in Devon, so this photo could be at a location in the same county. In the background there appears to be an un-bridged ford, so from that information someone could possibly point to the exact location - it that person is you, please let me know in the comments below.
