Despite the name, "metal nipple shields" (silver nursing cups) are not worn during feeding — they're healing tools used between feeds. This guide explains how silver cups differ from silicone shields and nipple covers, the science behind moist wound healing, a simple 3-step usage routine, common troubleshooting tips including tongue-tie, cost comparisons with disposable alternatives, and when to seek professional help for breastfeeding pain.
Three weeks into breastfeeding my first baby, I was sitting in my glider at 3 AM, tears streaming down my face, wondering if this was what medieval torture felt like. I'd tried lanolin cream, coconut oil, gel soothies that stuck to my bra (and once fell onto my baby's face) — nothing worked. A pair of silver nursing cups had been sitting unopened on my nightstand for days because I couldn't believe a piece of metal could possibly help. I was wrong. If you're in that same place right now, this complete guide to silver nursing cups covers everything you need to know.
Silver Cups vs. Silicone Shields
The most common misconception about "metal nipple shields" is that you wear them while nursing. Silver cups are entirely different from silicone nipple shields. Silicone shields go on during feeding to help babies with latch difficulties. Silver cups are healing tools worn inside your bra between feedings — they protect damaged nipples from clothing friction and create conditions that support recovery. For a detailed look at the pros and cons of metal nipple shields, see our companion guide.
Shield vs. Cover vs. Cup — Clearing Up the Names
You'll see these terms used interchangeably online, which adds to the confusion. A nipple shield is technically a silicone device worn during feeding. A nipple cover is a broad term that can mean fashion covers, silicone pasties, or silver cups depending on context. A silver nursing cup (sometimes called a metal nipple cup or metal nipple cover) is the between-feed healing tool this guide focuses on. When someone searches for "metal nipple shields," "metal nipple covers," or "metal nipple cups," they're almost always looking for silver nursing cups. For help deciding which option suits your situation, our nipple cover selection guide walks through the key differences.
How Silver Nursing Cups Actually Work
Silver nursing cups work through a recognized biological principle called moist wound healing. The Mayo Clinic and wound care research support the general principle that keeping wounds moist rather than dry promotes faster, less painful recovery. Here's how silver cups apply this:
Go Mommy cups are available in three material options: 925 Sterling Silver (most durable and scratch-resistant), 999 Fine Silver (highest purity, preferred for very sensitive skin), and 999 Trilaminate (combines high-purity silver surfaces with a reinforced core for everyday durability). All three are nickel-free. For a deeper comparison, see our solid vs. plated material guide.
How to Use Silver Cups: The 3-Step Routine
The first time I used my cups, I didn't realize you could add a drop of breast milk inside — that small detail made a noticeable difference. I wore mine between all daytime feeds and overnight during the first few weeks, then gradually less as discomfort improved. There's no fixed timeline; some mothers wear them for weeks, others for months. For hand expression techniques before applying the cups, Stanford Medicine's newborns program has excellent visual guides. For a detailed step-by-step with photos, see our complete usage guide.

Silver Cups and Tongue-Tie
If your baby has a tongue-tie (ankyloglossia), their restricted tongue movement can create unusual friction patterns on your nipples, leading to persistent soreness that doesn't improve with latch adjustments alone. Silver cups can help protect and soothe nipples damaged by tongue-tie related friction between feeds. However, the cups address the symptom (soreness), not the cause (restricted tongue movement). If you suspect tongue-tie, have your baby evaluated by a pediatrician or IBCLC — a frenotomy may be recommended. Silver cups work well as supportive care during the evaluation and recovery period.
Cleaning routine: The CDC recommends cleaning any breastfeeding accessories regularly. For silver cups, a daily rinse with warm water and mild soap is sufficient — no sterilization needed. Unlike disposable pads or creams, there's minimal ongoing maintenance.
Cost Comparison: Silver vs. Disposable Alternatives
The upfront cost of silver cups is higher than a box of disposable pads, but the math changes quickly over a breastfeeding journey. I spent about $50 on various creams, gel pads, and disposable supplies in my first two weeks alone — none of which resolved the underlying problem. For a full breakdown of silver cups vs. traditional remedies, see our side-by-side comparison.
Why Experts Distinguish Silver Cups from Shields
Some lactation consultants discourage nipple shields — but they're specifically referring to silicone shields used during feeding, which can interfere with milk transfer and potentially impact supply over time. Silver cups are a different category entirely: they're worn between feeds, don't touch the baby, and don't affect latch or milk transfer. For more on what experts say about this distinction, read our Silverettes and silver cup FAQ.
The key distinction: silver cups are supportive care, not a latch aid. If you're experiencing latch issues alongside nipple damage, the American College of Obstetricians and Gynecologists recommends working with a certified lactation consultant to address both.
My Experience: From Skeptic to Believer
The first night I used my cups, I woke up shocked — my nipples didn't hurt. I kept checking to make sure they were still there (new-parent brain is real). Unlike the gel pads that felt like a wet paper towel, or the creams that transferred onto everything, these stayed put and kept things dry.
I wore mine religiously for the first three weeks, then gradually less as my nipples toughened up. The delivery guy incident — when he noticed what looked like two metallic shapes through my nursing tank — was an early lesson in double-checking my outfit before answering the door. By the end of my journey, I'd become the friend who shows up at baby showers with the "unsexy" but essential gifts. Pairing the cups with our portable bottle warmer for on-the-go feeds was another game-changer for life outside the house.
One thing I want to be upfront about: every breastfeeding journey is different. Silver cups helped me significantly, but they're not a substitute for addressing underlying issues like poor latch, tongue-tie, or infection. They're a tool in your toolkit, not a cure-all — and they work best alongside proper support.
When to Seek Professional Help
Silver cups are supportive care for normal breastfeeding soreness and minor cracks. Some situations require professional evaluation beyond what any accessory can address:
Signs of infection (mastitis or thrush) — Fever, chills, flu-like symptoms, a painful red area that feels warm, or persistent itching and white patches on nipples or in baby's mouth. These require medical treatment.
Deep cracks that don't improve — If significant nipple damage persists after a week of consistent silver cup use and proper latch technique, there may be an underlying anatomical issue (tongue-tie, lip tie) or fit problem that needs assessment.
Pain during feeding despite correct latch — Silver cups address between-feed discomfort. Pain during feeding itself suggests a latch, positioning, or anatomical issue that a lactation consultant should evaluate.
Baby not gaining weight adequately — If your baby's weight gain is stalling, your pediatrician should assess whether supply, latch efficiency, or feeding volume is the issue.
The American Academy of Pediatrics recommends seeking help early when breastfeeding issues arise. Your local La Leche League chapter can connect you with certified lactation consultants in your area.

Frequently Asked Questions
Are metal nipple shields safe for my baby?
Yes. Silver nursing cups are made of 925 sterling or 999 fine silver, known for its natural properties in wellness and skin care. They are designed to be worn between feedings, not during them. Always remove the cup before latching your baby.
Do I breastfeed with the metal shield on?
No. Silver cups are healing tools worn inside your bra between feedings. They protect your nipples from friction and support skin recovery. Remove them before nursing so your baby can latch directly.
Do they really work for cracked nipples?
Many mothers report significant improvement. Silver creates a moist wound-healing environment that prevents painful scabs from forming. They also act as a physical barrier, stopping your bra from rubbing against sensitive skin.
How do I clean and care for them?
Rinse with warm water and mild soap daily. For tarnish, make a paste from baking soda and water, gently rub, and rinse. No elaborate sterilization needed. For a detailed guide, see our cleaning guide.
What is the difference between metal and silicone shields?
Silicone shields are used during feeding to help with latch difficulties. Metal (silver) cups are used between feedings to support healing of soreness and cracks. They serve completely different purposes.
Can I use them if I have a metal allergy?
Quality silver cups are made of nickel-free 925 sterling or 999 fine silver, which is generally hypoallergenic. If you have a known silver sensitivity, consult your doctor or do a patch test on your arm before wearing them on sensitive skin.
How do I know which size to buy?
Most silver cups come in Regular and XL sizes. The cup should cover your areola and nipple comfortably. If your areola diameter is larger than about 4.5 cm, choose the XL version.
Do I need to use nipple cream with them?
Most mothers find that a drop of breast milk inside the cup is sufficient. If your healthcare provider recommends a medicated cream, apply a thin layer and allow it to absorb before placing the cup. Many moms use cups alone without any cream.
How long do metal nipple shields last?
Solid silver cups last indefinitely. They can be used for your entire breastfeeding journey and saved for future children. Unlike disposable pads or silicone shields that degrade, silver doesn't wear out.
Can silver cups help with tongue-tie related soreness?
Silver cups can help protect and soothe nipples damaged by tongue-tie related friction between feeds. However, they don't address the tongue-tie itself. Have your baby evaluated by a pediatrician or IBCLC for the underlying issue.
What silver purity options are available?
Go Mommy offers 925 Sterling Silver (most durable), 999 Fine Silver (highest purity for sensitive skin), and 999 Trilaminate (combines purity with everyday durability). All three are nickel-free. See our full comparison guide for details.
Can I wear silver cups overnight?
Yes. Silver cups are safe for overnight wear. Use a snug nursing bra to keep them securely in place while you sleep. Many mothers find that overnight use is when the most noticeable healing occurs.
