Craftsman making notes about mother and child (10)
I believe the answer is:
stonemason
'craftsman' is the definition.
(I know that stonemason is a type of craftsman)
'notes about mother and child' is the wordplay.
'about' indicates anagramming the letters.
'mother' becomes 'ma' (ma can mean mother).
'and' says to put letters next to each other.
'child' becomes 'son' (male child).
'notes' is an anagram of 'stone'.
'stone'+'ma'+'son'='STONEMASON'
'making' acts as a link.
(Other definitions for stonemason that I've seen before include "Monumental worker" , "chipper?" , "Architectural carver" , "One working with, eg, granite" , "manual worker" .)
