A breastshield is provided that may be adhesively secured to a mother's breast for use in a breastpumping system. The adhesive is sufficiently strong so as to independently support the breastshield in position throughout a breast pumping session, including supporting the milk container, thereby enabling the mother to participate in other activities during the pumping session. The adhesive is advantageously of a type that is readily removed from the breast with the breastshield, and most preferably without leaving any significant residue.
