How to Collect Colostrum? | Antenatal Harvesting Steps

The correct technique uses a C-shape placement behind the nipple, gentle press-and-release motions, and patience—drops form slowly, never squirts. Below is the exact technique used by NHS and Cleveland Clinic guidelines.

How Hand Expression Works for Colostrum Collection

You use only your hands during pregnancy—breast pumps are unsafe for antenatal use. The goal is to stimulate the ducts behind the areola, not the nipple itself. Position your thumb above and four fingers below the breast, 2–3 cm from the nipple base (roughly two finger widths). Press back toward your chest, then gently squeeze thumb and fingers together. Release and repeat rhythmically.

Step-by-Step Protocol for Collecting Colostrum

1. Wash hands thoroughly with soap and water. Sterilize your syringe or small container.
2. Stimulate flow with a warm compress or warm shower, then massage the breast from outer edges toward the nipple for 1–2 minutes.
3. Form the C-grip: thumb on top, four fingers below, positioned 2–3 cm from the nipple base (not on the nipple).
4. Compress and release: press back toward the chest wall, squeeze fingers together, hold briefly, then release. Repeat rhythmically.
5. Rotate position around the areola if flow stops—different ducts respond to different angles.
6. Collect droplets by holding the syringe tip close to the nipple. Drops fall slowly; gently suction them if needed.
7. Switch sides when flow slows on one breast. Alternate between breasts each session.
8. Label and store the syringe with your name, date, and time. Seal in a re-sealable bag and freeze at -18°C.

Common Mistakes & Safety Warnings

• Pinching the nipple: causes pain, skin damage, and zero flow. Compress tissue behind the nipple, never the nipple itself.
• Sliding fingers over the skin: creates friction burns. Lift and press cleanly instead of sliding.
• Using a breast pump: unsafe during pregnancy. Hands-only expression is the standard for antenatal collection.
• Over-exerting: pain or uterine stimulation means you are squeezing too hard. This should not hurt—stop if it does.

If you find a colostrum collection kit that matches your needs, it typically includes sterile syringes and storage bags designed for this exact process.

How to Store and Handle Harvested Colostrum

Colostrum must be frozen within 24 hours if kept in the fridge. Use clearly labeled syringes inside a sealed bag to protect against freezer burn and cross-contamination. Avoid freezing in glass containers, as expansion can crack them. The stored colostrum is used as a supplement in the first days after birth before your milk comes in.
