Process for use with breastpump to initiate milk in breastfeeding, particularly for premature infants

A breastpump system comprising:

• a source of vacuum to cyclically deliver vacuum to a breastshield;
• at least one processor;
• memory storage;
• a first program stored on the memory storage which, when executed by the at least one processor causes the at least one processor to operate the source of vacuum, the first program comprising:
• providing a plurality of stimulation sequences for stimulating the breast using a rapid cycle rate;
• providing at least one expression sequence for extracting milk at a lower cycle rate;
• and
• operating the breastpump system according to at least one of a preset pattern of non-repeating sequences and a preset pattern of repeating sequences wherein certain of the repeating sequences occur in the pattern at unpredictable times to a user, the non-repeating sequences and the repeating sequences comprising the plurality of stimulation sequences and the at least one expression sequence, with periods of pauses between certain sequences.
