How to Choose a Manual Silicone Pump

A manual silicone pump is a simple, low maintenance tool best for catching let down and short sessions.

  1. Who it helps: Great for nursing moms who want to catch extra milk while feeding, reduce waste, or pump on the go without cords.
  2. Pick the right size: This 4 ounce pump is ideal for collecting let down and small expresses, not long pumping sessions intended to build a full stash.
  3. Using while nursing: Attach to the opposite breast during a feed to collect milk hands free, or use between feeds for short expression sessions.
  4. Cleaning and sterilizing: Boil 2 to 3 minutes or use a microwave sterilizer, and you can also place it in the dishwasher; avoid bleach and UV sterilizers.
  5. When to replace: Check regularly for tears or damage and replace if the silicone shows any signs of wear that could affect suction.
Frequently Asked Questions
How does the Haakaa Gen 2 pump work?

Place the flange over your nipple, center comfortably, then squeeze the base to create natural suction. Once milk flows, the pump collects milk silently without cords or batteries.

Is this pump safe for my baby?

Yes, the pump is made from 100 percent food grade silicone and is free from BPA, PVC, and phthalates.

Can I store milk in the pump with the flower stopper?

Yes, the flower stopper helps prevent spills and preserves milk for short term. For longer storage, transfer milk to labeled storage containers or bags and refrigerate or freeze following standard breast milk storage guidelines.

How should I clean and sterilize the pump?

Clean after each use, sterilize by boiling 2 to 3 minutes or use a microwave sterilizer. It is dishwasher safe. Do not use bleach based cleaners or UV sterilizers.

Will the pump fit my breast?

The soft, flexible silicone accommodates many breast shapes, but comfort and fit vary. Reposition as needed and stop if you feel pain, contacting a lactation consultant if concerns continue.
