Mother, The Artists Wife and son Kirill Boris Grigoriev (1886-1939)

The picture has something of this: baby, newborn, birth, child, suckling, people, son, crib, bed, blanket, offspring, nude, portrait, love, innocence, affection.
Perhaps it’s a painting of a woman sitting on a couch with a baby in her lap and holding a bottle of milk in one hand and a bottle in the other hand.
