Abstract: A wearable article (100) for supporting a baby (200) for lulling/breast-feeding purposes, comprises a flexible sleeve (10) with elongated shape with a first open end (15) and a second open end (25), opposite to each other, which define a introduction channel (30) that is configured to receive the arm (105) of a user (300), inserted through the first end (15) or the second end (25). In particular, the sleeve (10), defines an outer surface (11) in the introduction channel (30), which can contact directly the arm (105) of the user, and an outer surface (12) oriented towards the baby (200) and on which the baby head can rest.
