The Lansinoh® Single Electric Breast Pump was designed to mimic the baby’s natural feeding pattern and includes two phases: ‘let-down’ and ‘expression’. The ‘let-down’ or ‘stimulation’ phase uses quick and short suction to initiate the milk flow, while the ‘expression’ phase maximises milk flow through longer, deeper suction. In each of the two phases, mums can also adjust the suction strength, the pump offering a choice of 6 different suction levels.
