In-Depth Review
4 min readThe Haakaa Silicone Breast Pump is one of the most genuinely useful breastfeeding accessories ever made — not because it does something complex, but because it captures value that was previously always wasted.
The Let-Down Physiology
When a baby latches on one breast, the let-down reflex triggers both breasts simultaneously. The nursing side delivers milk to the baby. The non-nursing side releases milk that soaks into the nursing pad and is discarded. For most nursing parents at peak supply, this is 1–4 oz of milk per session — milk that took nutritional resources to produce and provides immunological value.
The Passive Collection Mechanism
The Haakaa attaches to the non-nursing breast with a gentle suction squeeze. It sits there without any attention, catching every drop of let-down as it flows. No motor, no assembly, no carrying equipment — just a $15 silicone cup that pays for itself in the first hour of use.
The Freezer Stash Foundation
Many nursing parents who build significant freezer stashes report the Haakaa as their primary milk banking tool. One session of active pumping with an electric pump yields 2–5 oz. Adding a Haakaa to every nursing session yields an additional 1–3 oz passively — potentially doubling bank rate with zero additional effort.
Verdict
Buy this before you leave the hospital. At $15, it is the highest-value-per-dollar purchase in the entire baby product category.
Who It's For
The Haakaa Silicone Breast Pump Gen 2 is the right choice when choosing a breast pump if:

Safety Standards & Certifications
Breast pumps classified as milk-expression devices are regulated by the FDA as Class II medical devices, requiring 510(k) clearance. All parts that contact milk must be BPA-free and phthalate-free. Under the Affordable Care Act, most insurance plans are required to cover a breast pump — check your insurer before purchasing.

How It Compares
Haakaa Silicone Breast Pump Gen 2 vs Spectra S1 Plus Electric Breast PumpThe Spectra S1 Plus Electric Breast Pump is the higher-priced option with a score of 9.2/10. The extra cost buys rechargeable battery — pump anywhere without a power outlet. The Haakaa Silicone Breast Pump Gen 2 at the budget tier delivers the core function at a lower price — choose it if budget is a constraint.
Also consider: The Spectra S2 Plus (mid-range, 9.1/10) — The Spectra S2 Plus delivers hospital-grade performance at a fraction of the rental cost.Value for Money
Our score of 9/10 reflects an exceptional product — among the top in its category. At its price point, the Haakaa Silicone Breast Pump Gen 2 represents excellent value — the core function is delivered without the premium price tag of category leaders. For budget-conscious families who need reliable performance over luxury features, this is the right choice.
Parent Tips
- Be aware of the limitation: Passive only — not suitable as primary pump for supply building. If this feature is essential for you, factor it into your buying decision.
- Before buying, account for this known limitation: Can be knocked off if not carefully positioned. Understand whether this affects your specific situation.
- Flange size matters more than any other pump component — measure nipple diameter and size up by 2–3mm for the correct fit.
- Clean pump parts in hot soapy water after every session — dishwasher cleaning degrades silicone parts faster.

Frequently Asked Questions
How does the Haakaa collect milk without being a pump?
The silicone body creates a gentle suction when you squeeze and release it against the breast. This passive suction catches the let-down reflex milk that flows from the non-nursing side during a feed. Without the Haakaa, this milk soaks into a breast pad and is wasted.
Can the Haakaa replace an electric pump?
No — the Haakaa collects milk that flows on its own during let-down. It does not actively extract milk or maintain supply like an electric pump. It is a supplement to breastfeeding, not a replacement for active pumping.
How much milk does it collect per session?
Typically 1–4 oz per nursing session depending on milk supply and how strong let-down is. Most nursing parents collect enough in 2–3 sessions to fill a supplementary bottle. Over 6 months of nursing, this adds up to hundreds of ounces of milk that would otherwise be wasted.
