This is an incomplete set of child therapy "equipment" used by professionals to observe their clients navigate a scenario and reveal feelings. It was used extensively in child psychology in Europe; I don't know if it is still " a thing" but it could be most useful in observation and exploration.
It includes a family of five, a kitchen table, side board, a free standing sink, a stove- microwave and sink unit as well as assorted extras some of which make sounds and light up.
I believe some subsidiary of the Froebel franchise created this set, but there is no identification on any of the pieces.
