Avent Isis Breast Pump

Avent Isis Breast Pump

This was the most comfortable, effective manual pump I used. The pump emulates the suckling of the baby and the suction cup is designed to stimulate the flow of milk. Also, considering how effective it is, $50 is very cheap. If you pick this up, buy the Avent microwave sterilizer I recommended as well. The pump fits in there, making it easy to clean and sterilize.
