Kim adds: Grannie holding Mum for a christening photograph perhaps in a studio (see curtain behind – though perhaps not with stairs in bottom left corner.  This would have been in July/Aug/Sept 1923 as baby is able to support own head; so Mum 3 or 4 months old (born 2/6/23) and Grannie still only 18 years old as she was born 2nd October 1904.
