A disposable absorbent insert free of transversely extending side panels comprising: a liquid permeable topsheet; a liquid impermeable backsheet; and an absorbent core comprising absorbent material therein and being sandwiched between said topsheet and backsheet; wherein the insert comprises a perimeter formed by first and second transverse edges (6, 7) and first and second longitudinal edges (8, 9) connecting the first and second transverse edges (6, 7); a longitudinal centerline (y) extending substantially parallel to said first and second longitudinal edges (8, 9) and interposed therebetween such to divide said insert into a first longitudinal half between said longitudinal centerline (y) and said first longitudinal edge and a second longitudinal half between said longitudinal centerline (y) and said second longitudinal edge; and a transverse centerline (x) extending substantially parallel to said first and second transverse edges (6, 7) and interposed therebetween such to divide said insert into a first transverse half between said transverse centerline (x) and said first transverse edge and a second transverse half between said transverse centerline (x) and said second transverse edge; characterised in that the insert comprises a wetness indicator that is viewable from a garment-facing side of the backsheet and in that said insert is joinable to a re-usable outer shell and wherein the wetness indicator comprises a composition that changes appearance and/or colour when contacted with urine, the composition comprising a pH indicator and/or a water soluble dye and wherein the absorbent core comprises a core wrap enclosing the absorbent material therein, and wherein the wetness indicator is positioned between a garment-facing side of the core wrap and a body-facing surface of the backsheet, and wherein the wetness indicator extends along the longitudinal centerline (y) and from about the transverse centerline (x) to a first terminal position in a direction towards the first transverse edge and extends from about the transverse centerline (x) to a second terminal position in a direction towards the second transverse edge; wherein the distance between the first terminal position and the first transverse edge is less than the distance between the second terminal position and the second transverse edge or vice versa. a liquid permeable topsheet; a liquid impermeable backsheet; and an absorbent core comprising absorbent material therein and being sandwiched between said topsheet and backsheet; wherein the insert comprises a perimeter formed by first and second transverse edges (6, 7) and first and second longitudinal edges (8, 9) connecting the first and second transverse edges (6, 7); a longitudinal centerline (y) extending substantially parallel to said first and second longitudinal edges (8, 9) and interposed therebetween such to divide said insert into a first longitudinal half between said longitudinal centerline (y) and said first longitudinal edge and a second longitudinal half between said longitudinal centerline (y) and said second longitudinal edge; and a transverse centerline (x) extending substantially parallel to said first and second transverse edges (6, 7) and interposed therebetween such to divide said insert into a first transverse half between said transverse centerline (x) and said first transverse edge and a second transverse half between said transverse centerline (x) and said second transverse edge; characterised in that the insert comprises a wetness indicator that is viewable from a garment-facing side of the backsheet and in that said insert is joinable to a re-usable outer shell and wherein the wetness indicator comprises a composition that changes appearance and/or colour when contacted with urine, the composition comprising a pH indicator and/or a water soluble dye and wherein the absorbent core comprises a core wrap enclosing the absorbent material therein, and wherein the wetness indicator is positioned between a garment-facing side of the core wrap and a body-facing surface of the backsheet, and wherein the wetness indicator extends along the longitudinal centerline (y) and from about the transverse centerline (x) to a first terminal position in a direction towards the first transverse edge and extends from about the transverse centerline (x) to a second terminal position in a direction towards the second transverse edge; wherein the distance between the first terminal position and the first transverse edge is less than the distance between the second terminal position and the second transverse edge or vice versa.
