Abstract: This study addresses the issue of mother/child co-prisoners, from a psychological point of view. In general, children living in prisons live in unfavourable socio-environmental conditions that affect their natural and serene development, leading the public opinion to consider them real "innocent prisoners". As is well known, prison deprives the mother of her total autonomy in the management of her child and alters the natural daily rhythms of life that characterise a free and social life.
