A method of using a system to collect colostrum from a breast of a human and using at least part of the system to dispense the colostrum to an newborn involves: coupling an interface member with a suction member to form at least part of the system; positioning the interface member in contact with or near the breast; expressing colostrum from the breast, into the interface member; applying suction force to the interface member, using the suction member, to draw the colostrum into the suction member; detaching the interface member from the suction member; and dispensing the colostrum to the newborn from the suction member.
