Set up the Haakaa Gen 3 Pump and Bottle Pack step by step: attach the flange, express, then twist on a bottle or sealing disk for feeding and storage.

Quick answer

Set up the Haakaa Gen 3 by attaching the flange to the silicone bottle, squeezing to create suction, and then twisting the flange off to swap in a bottle nipple or sealing disk. The key is to keep every connection clean and dry before each use.

Why the twist-and-swap design changes your routine

Most pumps require you to transfer milk from a collection container into a separate bottle. The Haakaa Gen 3 system lets you express directly into the same 160 ml/6 oz silicone bottle you can later feed from or seal for storage. That reduces the number of parts to wash and the chances of spilling milk during transfers.

Because the bottles are made from food-grade silicone, they are soft and flexible. That can be helpful for hand expression or for babies who prefer a softer bottle, but it also means the bottle may not stand upright as rigidly as a hard plastic bottle when full. Plan to set it down carefully or use a stable surface.

What the pack includes and what it does not

The Haakaa Gen 3 Pump and Bottle Pack includes two 6 oz/160 ml silicone baby bottles. The pump flange is part of the system and twists onto the bottle. The pack also includes a sealing disk, which lets you close the bottle for storage. What the catalog does not specify is the nipple flow rate or the exact number of nipple attachments included, so check the packaging or product listing if you need that detail before buying.

This is a manual suction pump, not an electric or hands-free pump. You create suction by squeezing the flange, and you control the rhythm by hand. That makes it portable and quiet, but it also means you cannot multitask as freely as you might with a hands-free electric setup.

Step-by-step setup and use

Wash and sterilize all parts before first use: Disassemble the flange, bottle, and sealing disk. Wash in warm soapy water, rinse thoroughly, and sterilize according to the manufacturer's instructions. Let everything air-dry completely. Common mistake: assembling while parts are still wet, which can make the suction slip. Keep a clean, dry towel or drying rack dedicated to pump parts to avoid recontamination.
Attach the flange to the bottle: Twist the flange onto the top of the silicone bottle until it is snug. Do not overtighten, as silicone can stretch. Check that the flange sits flat and the bottle is upright. Common mistake: cross-threading the flange, which causes air leaks and weak suction. Give the flange a gentle tug to confirm it is seated before you begin pumping.
Create suction and position the flange: Squeeze the flange to expel some air, then center it over your nipple so the tunnel forms a seal. Release the squeeze to create suction. You should feel a gentle pull, not pain. Common mistake: squeezing too hard or placing the flange off-center, which can cause discomfort or poor milk flow. If it hurts, break the seal with a finger and reposition before continuing.
Express milk and monitor the bottle: Let the suction do the work, or gently squeeze the bottle in a rhythm to encourage let-down. The bottle holds 160 ml/6 oz, so watch the level and stop before it reaches the flange. Common mistake: overfilling, which can cause milk to back up into the flange and reduce suction. Have a clean cloth nearby to wipe drips and keep the flange dry for a secure seal.
Twist off the flange and swap in a nipple or sealing disk: When you finish, remove the flange by twisting gently. If feeding right away, twist on a bottle nipple (if included) until snug. For storage, twist on the sealing disk. Common mistake: forgetting to label the bottle with the date and time before storing. Use a piece of tape or a bottle label to record the expression date; use refrigerated milk within the timeframe your healthcare provider recommends.
Clean immediately after each use: Disassemble all parts and wash in warm soapy water, using a bottle brush for the bottle and a small brush for the flange tunnel. Rinse well and air-dry. Common mistake: letting milk residue dry in the flange, which is harder to clean and can harbor bacteria. If you cannot wash right away, rinse the parts in cool water and soak until you can clean them properly.
