Child care item (1; 1') intended to be brought to the mouth by a child, the child care item (1; 1') comprising: - a seat (2; 2') having a front face (2a; 2a') and a rear face (2b; 2b') opposite one another, the seat (2; 2') including a recess (4; 4') internal thereto, - at least one tip (35; 35') including a base (40; 40') and a body (36; 36') intended to be placed in the mouth of the child, the tip (35; 35') being mounted in a removable manner on the seat (2; 2'), the base (40; 40') being received inside the recess (4; 4') of the seat (2; 2') and the body (36; 36') of the tip (35; 35') extending from the front face (2a; 2a') of the seat (2; 2') when the tip (35; 35') is mounted on the seat (2; 2'), and - a device for locking the base (40; 40') of the tip (35; 35') in the recess (4; 4') of the seat (2; 2'), the locking device including at least one locking member (65; 65') having a stop surface (65e; 65e') and mounted on one of the elements selected from the group consisting of the base (40; 40') of the tip (35; 35'), and the seat (2; 2'), and at least one abutment member (45; 45') having an abutment surface (45a; 45a') and provided on the other element selected from the group consisting of the base (40; 40') of the tip (35; 35'), and the seat (2; 2') in order to engage with the locking member (65; 65'), the locking member (65; 65') being capable of being displaced relative to the abutment member (45; 45') between a locking position in which the stop surface (65e; 65e') interferes with the abutment surface (45a; 45a') to retain the base (40; 40') of the tip (35; 35') inside the recess (4; 4') of the seat (2; 2'), and a retracted position in which the stop surface (65e; 65e') does not interfere with the abutment surface (45a; 45a') in order to be able to displace the tip (35; 35') relative to the seat (2; 2'), the child care item (1; 1') being characterised in that the recess (4; 4') opens out onto the front face (2a; 2a') of the seat (2; 2') via an assembly opening (26; 26'), the assembly opening (26; 26') and the base (40; 40') of the tip (35; 35') being shaped so as to allow insertion of said base (40; 40') into the recess (4; 4') of the seat (2; 2') through said assembly opening (26; 26') via the front face (2a; 2a') of the seat (2; 2'). - a seat (2; 2') having a front face (2a; 2a') and a rear face (2b; 2b') opposite one another, the seat (2; 2') including a recess (4; 4') internal thereto, - at least one tip (35; 35') including a base (40; 40') and a body (36; 36') intended to be placed in the mouth of the child, the tip (35; 35') being mounted in a removable manner on the seat (2; 2'), the base (40; 40') being received inside the recess (4; 4') of the seat (2; 2') and the body (36; 36') of the tip (35; 35') extending from the front face (2a; 2a') of the seat (2; 2') when the tip (35; 35') is mounted on the seat (2; 2'), and - a device for locking the base (40; 40') of the tip (35; 35') in the recess (4; 4') of the seat (2; 2'), the locking device including at least one locking member (65; 65') having a stop surface (65e; 65e') and mounted on one of the elements selected from the group consisting of the base (40; 40') of the tip (35; 35'), and the seat (2; 2'), and at least one abutment member (45; 45') having an abutment surface (45a; 45a') and provided on the other element selected from the group consisting of the base (40; 40') of the tip (35; 35'), and the seat (2; 2') in order to engage with the locking member (65; 65'), the locking member (65; 65') being capable of being displaced relative to the abutment member (45; 45') between a locking position in which the stop surface (65e; 65e') interferes with the abutment surface (45a; 45a') to retain the base (40; 40') of the tip (35; 35') inside the recess (4; 4') of the seat (2; 2'), and a retracted position in which the stop surface (65e; 65e') does not interfere with the abutment surface (45a; 45a') in order to be able to displace the tip (35; 35') relative to the seat (2; 2'),
