Exactly which baby and breastfeeding items qualify for HSA and FSA reimbursement, what the IRS eligibility test is, which items need a Letter of Medical Necessity, what common mistakes cost families hundreds of dollars, and how to build a first-year spending plan that maximizes your pre-tax benefit.
Most families with an HSA or FSA account are leaving hundreds of dollars on the table every year — not because they are not spending the funds, but because they do not know which baby items qualify. Diapers do not. Formula does not. But breast pump accessories, lactation consultant fees, silver nursing cups, thermometers, and nasal aspirators all do.
The difference between an eligible and an ineligible purchase comes down to a single IRS test: is the item primarily used to treat or prevent a specific medical condition? If yes, it is likely eligible. If it is a general comfort, hygiene, or wellness item, it is not. This guide applies that test to the most common baby and breastfeeding purchases — so you can make informed decisions before checking out.
HSA vs. FSA: Which Account Do You Have?
Both HSA and FSA accounts let you pay for eligible healthcare expenses with pre-tax dollars, effectively giving you a discount equal to your tax rate on every qualifying purchase. At a 25% effective tax rate, $1,000 of eligible baby expenses costs you $750 out of pocket — you save $250 automatically.
How to Use Your HSA or FSA for Baby Items
- Pay with your HSA/FSA debit card directly at checkout. For clearly eligible categories — breast pump parts, thermometers, nasal aspirators — the debit card works at most pharmacies and major retailers. Keep the receipt even when paying with the card, in case of audit.
- Pay out of pocket and submit for reimbursement. If your card is declined — which can happen when a retailer's payment system does not automatically recognize the eligible category — pay with a personal card, log in to your benefits portal (WageWorks, Fidelity, Optum, HealthEquity, etc.), upload your receipt, and submit. Reimbursement typically processes in 3 to 5 business days.
- Keep every receipt. The IRS requires documentation for all HSA and FSA expenses. Even for purchases made with your debit card, store receipts digitally. Photo them immediately at checkout.
- For Go Mommy products specifically: purchase directly at gomommyus.com — not through Amazon — to receive a reimbursement-ready invoice containing the "Breastfeeding Supply / Lactation Aid" category code your plan administrator needs. For full reimbursement instructions, see our HSA/FSA Reimbursement Guide.
- FSA year-end planning. Set a reminder for November 1st to check your FSA balance. Unspent FSA funds expire December 31st for most plans. Common year-end purchases: replacement pump accessories, silver nursing cups, thermometers, nasal aspirators, first aid supplies.
Breastfeeding Supplies That Are HSA/FSA Eligible
Breastfeeding supplies are among the most broadly eligible HSA and FSA expense categories, supported explicitly by the ACA mandate. The following items qualify under most plans without requiring a Letter of Medical Necessity.
- Breast pump (electric, manual, or hospital-grade rental). The ACA mandates that most insurance plans provide a breast pump at no cost — but accessories are separately eligible for HSA/FSA reimbursement even if the pump itself was covered by insurance.
- Pump accessories. Flanges, valves, tubing, membranes, and breast shields. Replace membranes every 4 to 6 weeks for optimal pump performance — each replacement qualifies.
- Nursing pads (disposable and reusable), nipple shields, and nipple balm. All eligible as breastfeeding supplies under IRS Publication 502. For our full nursing pad guide, see the comparison of disposable, reusable, and silver cup options.
- Silver nursing cups. Worn between feeds to protect nipple integrity during breastfeeding — classified as a lactation aid. Go Mommy® Silver Nursing Cups in 925 Sterling, 999 Pure Solid, and 999 Trilaminate variants are all eligible. Our invoice includes the required Lactation Aid category code. For help choosing the right variant, see our buyer's guide.
- Breast milk storage bags and bottles. Eligible as breastfeeding supplies. For complete storage rules, see our breast milk storage guidelines.
- Haakaa and silicone pumps. Eligible as breast pump accessories or manual pumping devices.
- IBCLC lactation consultant fees. Consultation fees paid to an International Board Certified Lactation Consultant are eligible medical expenses. This is often the highest-value single eligible expense in the first 6 weeks.

What Is NOT Eligible: Common Costly Mistakes
The most common HSA and FSA mistakes involve items that feel like healthcare expenses but do not meet the IRS medical necessity standard. Attempting to submit these for reimbursement can result in denied claims, and improper use of HSA funds is subject to income tax plus a 20% penalty.
The IRS Test — Applied Quickly
Ask: "Would I buy this item if I did not have this medical condition?" If yes — it is probably not eligible. A thermometer fails this test (you buy it specifically because your child could get sick). Diapers pass it (you would buy them regardless). When in doubt, confirm with your plan administrator before purchasing.
Letter of Medical Necessity: When You Need One
A Letter of Medical Necessity (LMN) is a written statement from your healthcare provider confirming that a specific item or service is medically necessary. LMNs expand eligibility to items that are otherwise borderline.
- Items that commonly require an LMN: nursing bra ("required for breastfeeding which is medically recommended"), hands-free pumping bra ("necessary for continued pumping due to return to work"), nursing pillow ("required to support correct latch and prevent musculoskeletal strain"), lactation supplements for documented supply insufficiency.
- How to get an LMN. Ask your OB, midwife, or IBCLC at your 6-week postpartum visit. Most providers write these without a dedicated appointment — a patient portal message is sufficient.
- What the LMN needs to include. Your name, the specific item or category, the medical condition or indication, your provider's name and signature, and a date. A simple letter on provider letterhead is accepted by most plan administrators.
- LMN validity period. Most plans accept LMNs for one to three years. Ask your plan administrator how long an LMN remains valid.
First-Year Spending Plan: Maximize Your Benefit
- Before birth (third trimester). Breast pump accessories, silver nursing cups, nipple balm, and breast milk storage bags — all high-certainty purchases every breastfeeding mother will use.
- Birth through 6 weeks. IBCLC lactation consultant fees — typically the highest single eligible expense. Nursing pads (consumption peaks here). Peri bottle and postpartum recovery supplies with LMN. Infant acetaminophen.
- Months 2 through 6. Replacement pump membranes and valves (every 4 to 6 weeks). Baby sunscreen at 6 months. Nasal aspirator replacement parts.
- Months 7 through 12. Teething gel and infant oral pain reliever. Pediatric dental care items. November: check FSA balance and sweep remaining funds before December 31st.
- Estimated first-year eligible spend. A typical breastfeeding family spends approximately $700 to $900 in eligible baby and breastfeeding expenses in year one — representing $175 to $225 in tax savings at a 25% bracket.
Year-End FSA Sweep: Don't Lose Your Benefits
For FSA holders, the period between November 1st and December 31st is the single most important planning window. Unspent FSA funds — above the plan's rollover limit, usually $660 — are forfeited.
- November 1st: check your FSA balance. Log in to your benefits portal and calculate what you need to spend before December 31st.
- Stock eligible items you will definitely use. Thermometer, nasal aspirator, first aid kit resupply, infant acetaminophen, saline nasal drops, baby sunscreen — all eligible, all consumable.
- Replace worn pump accessories. Membranes, valves, and flanges in use for more than 4 months should be replaced — legitimate eligible expense.
- Silver nursing cups as a year-end purchase. If you are still breastfeeding or planning a second child, silver nursing cups are a one-time purchase with multi-year use. Purchase before December 31st to use expiring FSA funds on a durable, eligible lactation aid.
- Schedule any outstanding IBCLC visits. IBCLC consultation fees can absorb a significant FSA balance in a single visit.

Frequently Asked Questions: HSA/FSA Eligible Baby Items
Are silver nursing cups HSA and FSA eligible?
Yes. Silver nursing cups qualify as a lactation aid under IRS Publication 502. Go Mommy provides a reimbursement-ready invoice with the Lactation Aid category code. Most plans do not require an LMN for this item.
What is the difference between HSA and FSA for baby expenses?
Both cover the same eligible expenses with pre-tax dollars. HSA funds roll over indefinitely — FSA funds typically expire December 31st. For baby expenses, FSA holders need to plan their election amount carefully each November.
My insurance covers my breast pump — can I still use HSA/FSA for accessories?
Yes. Insurance covering the pump does not affect your ability to use HSA or FSA funds for accessories — flanges, valves, tubing, membranes, and storage bags are all separately eligible.
Do I need a Letter of Medical Necessity for nursing bras?
Yes, for most plans. Nursing bras require an LMN from your OB or midwife confirming breastfeeding is medically recommended. Ask at your 6-week postpartum visit — most providers write these readily.
Is a portable bottle warmer HSA or FSA eligible?
No. A portable bottle warmer is a general convenience item for warming milk, not a medical device or breastfeeding supply under IRS rules. It does not meet the medical necessity test required for HSA/FSA eligibility.
What baby items are NOT HSA/FSA eligible?
Diapers, wipes, standard formula, baby clothing, standard video monitors, portable bottle warmers, cosmetic baby wash/lotion, and gym memberships. The IRS test: is the item primarily for treating or preventing a specific medical condition?
When should I start using HSA/FSA funds for baby items?
Start in the third trimester. Pump accessories, silver nursing cups, nipple balm, and storage bags can be purchased before birth. After delivery, IBCLC fees are the highest-value single eligible expense.
How do I submit an HSA/FSA claim?
Log in to your benefits portal, navigate to reimbursement, upload your receipt or invoice, select the eligible category, enter the amount, and submit. Processing takes 3 to 5 business days. Keep all receipts.
Can I use last year's HSA funds for baby expenses this year?
Yes. HSA funds roll over indefinitely — there is no deadline. FSA funds do not roll over the same way — most plans expire annually, though some allow up to $660 rollover.
