boshi-e (母子絵) (genre )
A little known sub-genre of Japanese art. Literally it means "a mother and child" painting or print. But by extension, it has come to include any woman attendant to a child, either a relative, friend or servant.
The Kumon Museum of Children's Ukiyo-e note regarding boshi-e:
"A type of decorative ukiyo-e print that depicts the daily loving life of mother and child, including scenes of nursing, diaper-changing, bathing, hairdressing and playing with toys. The concept of "children are riches" can be found in many prints. As well as mothers, sisters and other women are often depicted in some prints and these are also considered boshi-e." (JSV)
