We have seen mothers receive a nipple shield from a nurse, get no instructions with it, and spend days guessing whether they are using it correctly. A nipple shield is a thin silicone cover worn over the nipple during breastfeeding. Applied correctly, it helps babies latch when direct feeding is not working. This guide covers sizing, application, latch, and when to stop using it.
Key Takeaways
- Size matters: A shield that is too large or too small reduces milk transfer. Measure your nipple diameter before choosing a size.
- Apply it inside out: Turning the shield halfway inside out before placing it helps it grip the breast and stay in position during feeding.
- Shield does not replace latch work: The baby still needs to take the nipple and surrounding shield into the mouth deeply. A shallow latch over a shield is still a shallow latch.
- Use it as a bridge, not a permanent fix: Most mothers can wean off a shield within 4 to 6 weeks as latch improves.
- Sterilize before first use: After that, wash thoroughly after every feed and sterilize once daily.
When a nipple shield is the right tool
A nipple shield is not for every breastfeeding difficulty, but there are five situations where it is genuinely useful.
Latch difficulty in newborns:
Some babies, especially in the first two weeks, cannot maintain a latch on a soft nipple. A firm silicone shield gives them a consistent surface to grip.
Flat or inverted nipples:
When the nipple does not protrude enough for the baby to latch onto, a shield adds the projection the baby needs. Use it alongside a nipple corrector for faster long-term improvement.
Nipple soreness or cracking:
A shield reduces direct friction on damaged skin during feeds, allowing healing while breastfeeding continues.
Premature or small babies:
Premature babies often have a weak suck and a smaller mouth. A firm shield is easier for them to grip than soft breast tissue.
Engorgement:
A very full, hard breast flattens the nipple and makes latching harder. A shield helps the baby get started until the breast softens after the first letdown.
Choosing the right shield size
Shield size refers to the diameter of the nipple tunnel, not the overall shield size. Measure your nipple diameter at its base after a feed, when it is at its most extended. Use a ruler or a soft measuring tape.
| Nipple diameter | Recommended shield size |
|---|---|
| Under 16mm | 16mm shield |
| 16mm to 20mm | 20mm shield |
| 20mm to 24mm | 24mm shield |
| Over 24mm | 24mm or consult a lactation consultant |
Inside the shield tunnel, your nipple should move freely without rubbing the sides. If the tunnel walls press against your nipple during feeding, size up. If your nipple does not fill the tunnel and suction feels weak, size down.
Step-by-step: how to apply a nipple shield
Follow these steps before every feed
- Wash hands thoroughly with soap and water before handling the shield.
- Turn the brim of the shield halfway inside out so it folds back on itself. This creates a cup shape that helps it grip the breast.
- Center the shield over your nipple and press the brim down onto the areola. The nipple should sit inside the tunnel without forcing it in.
- Roll the folded brim back outward onto the breast. The suction created as it unfolds pulls the nipple gently into the tunnel and holds the shield in place.
- Check that the cut-out section, if your shield has one, is positioned toward your baby's nose. This allows skin-to-skin contact between the baby's upper lip and your breast during feeding.
- Offer the breast to your baby immediately. The shield holds best when feeding starts within 30 seconds of application.
How to ensure your baby latches over the shield
A nipple shield does not guarantee a good latch. The baby needs to take the nipple tunnel and a good portion of the surrounding shield into the mouth to transfer milk effectively.
Watch for these signs that the latch over the shield is working: the shield stays in place without you holding it, you can see the baby's jaw moving in a wide, rhythmic pattern, and you can hear swallowing after the first minute of feeding. If the shield keeps falling off, the baby is latching onto just the tip. Reposition so more of the areola is in the mouth before the baby closes.
A semi-circle cut-out design, like the nipple shield semi-circle, helps here. The cut-out sits under the baby's nose and allows the baby to smell the breast, which encourages a wider mouth opening and a deeper latch over the shield.
For mothers whose babies need more support transferring milk through a shield, the double layer nipple shield provides additional structure. The firmer feel gives weaker-sucking babies, including premature infants, a more consistent surface across a longer feed.
Deepsea shield options: which one suits you
| Feature | Semi-circle shield | Double layer shield | Prime nipple shield |
|---|---|---|---|
| Design | Cut-out for skin contact | Two-layer silicone | Standard full shield |
| Best for | Latch difficulty, inverted nipples | Premature or weak-suck babies | General soreness, engorgement |
| Skin contact | Yes, through cut-out | Minimal | Minimal |
| Thickness | Thin, flexible | Firmer | Standard |
| Recommended use | Daily breastfeeding support | Extended or specialist use | Short-term soreness relief |
The Prime Nipple Protector Shields are the most practical starting point for mothers using a shield for general soreness or engorgement. Move to the semi-circle design if latch depth is the primary concern.
How long to use a shield and when to wean off
A nipple shield is a bridge, not a long-term solution. Extended use without working toward direct latch can reduce nipple stimulation, which over time may affect supply. Most mothers are ready to start weaning off a shield between 3 and 6 weeks postpartum as the baby's latch strengthens and nipple shape improves.
How to wean off gradually
Start each feed without the shield. If the baby latches within the first two minutes and milk flows, continue without it. If the baby cannot latch or becomes distressed, apply the shield and complete the feed. Over several days, the window of shield-free feeding extends. Most mothers achieve full shield-free feeding within one to two weeks of consistent attempts.
Do not rush this. A baby who is feeding well with a shield is getting milk. That is the priority. Weaning off happens when both mother and baby are ready.
Cleaning and sterilizing your nipple shield
Rinse the shield in cold water immediately after every feed. Cold water first, not hot, to prevent milk proteins from setting inside the silicone. Then wash with warm soapy water using clean fingers or a soft brush. Rinse thoroughly.
Sterilize the shield before its first use and once per day during regular use. Boil in water for 5 minutes or use a microwave steam sterilizer. In Pakistan's heat, air-dry completely on a clean surface before storing. Never store a damp shield in a closed case between feeds. Moisture trapped in silicone in warm temperatures creates a hygiene risk within hours.
Frequently asked questions
Does using a nipple shield reduce milk supply?
Used correctly with a good latch, a nipple shield does not reduce supply. Milk supply drops only if the breast is not being emptied fully at each feed. If the baby's latch over the shield is shallow, less milk transfers and supply can drop over time. Check latch depth at every feed and watch for weight gain as confirmation that feeding is effective.
Can my baby feel my body temperature through a silicone shield?
Silicone is a mild insulator so the direct skin warmth of the nipple is reduced. This is one reason the cut-out design exists: it allows direct skin contact between the baby's nose and upper lip and your breast, which maintains some of the sensory connection and helps trigger letdown. Warming the shield briefly in your hand or in warm water before applying can partially offset this.
What if the shield keeps falling off during feeding?
The shield is not gripping the breast firmly enough. The inside-out application technique creates suction that holds it in place. If it still falls off, the brim may not be making full contact with the areola. Try applying with slightly damp skin, which improves suction. Also check shield size: a shield that is too large for the nipple does not create a tight enough seal to stay in position.
Is it safe to use a nipple shield at every single feed long-term?
It is safe in the short term. Beyond 6 to 8 weeks, continued dependence on a shield without working toward direct latch warrants a check-in with a lactation consultant. The concern is not safety but whether the baby is transferring milk efficiently enough and whether supply is being maintained. Most mothers do not need long-term shield use once the underlying latch issue is addressed.
How do I know the baby is getting enough milk through a shield?
Track wet nappies: 6 or more per day after day 5 indicates adequate intake. Track weight gain: steady gain of 150 to 200 grams per week in the first three months is a reliable sign. If feeds feel one-sided, the baby comes off frequently, or weight gain is slow, assess latch depth over the shield first before assuming supply is the problem.
