The current GAPS wet-nursing chapter gives one central standard: choose a healthy breastfeeding woman. Dr. Natasha Campbell-McBride says the best indicator is the health of the donor’s own baby. If that baby is healthy and thriving, the book says the woman’s milk is likely to be healthy.[1]
The expanded earlier book adds two direct questions: does she have any current health problems, and is she taking any medications? The current book keeps health as the governing qualification and adds the thriving-baby indicator. It does not carry the earlier book’s “young woman” description forward as a separate age requirement.[2][1]
For the full sequence, start with the complete GAPS guide to wet nursing and donor milk, which explains where wet nursing and expressed donor milk sit in the preference order before you use this screening checklist.
The Core GAPS Screen
| Question | What the Source Says | What to Record |
|---|---|---|
| Is the woman healthy? | The current book says to choose a healthy wet nurse.[1] | Her description of her current health |
| Is her own baby healthy and thriving? | The current book says this is the best indicator that the woman is healthy, and then says her milk is likely to be healthy.[1] | What she reports and what you can observe about her baby’s wellbeing |
| Does she have a current health problem? | The expanded earlier book says to look for women without health problems.[2] | Any current condition she identifies |
| Is she taking medication? | The expanded earlier book names no medication use in its donor description.[2] | Current medications she identifies |
Start with these GAPS questions, then arrange medical screening before sharing milk. A donor’s healthy appearance or thriving baby cannot rule out infection. The Academy of Breastfeeding Medicine’s guidance for healthy, full-term infants includes health history, medication and herbal-product compatibility, infectious-disease screening, substance and tobacco use, and safe milk handling. It applies screening to wet nurses as well as expressed-milk donors.[5]
What the Thriving-Baby Indicator Means
Campbell-McBride uses the donor’s own baby as a visible indicator of the woman’s health. The current chapter says a healthy, thriving baby is the best indicator that the woman is healthy, and then says her milk is likely to be healthy and useful to another baby.[1]
Bring the donor’s health history and available prenatal or postnatal screening results to the baby’s clinician. Review HIV, hepatitis B, and, where relevant, HTLV-1 results, along with medicines and supplements. Do not ask a donor to stop a prescription to qualify; check whether it is compatible with breastfeeding.[5]
Questions That Are Separate From the Health Screen
Diet, direct nursing versus expressed milk, travel distance, storage, warming, and backup coverage still need answers. They are practical planning questions rather than substitutes for the health screen.
- Diet: use the GAPS diet for wet nurses and milk donors when the donor is following GAPS.
- Direct or expressed milk: the current book prefers direct nursing but still places pumped, refrigerated, and rewarmed donor milk ahead of formula.[1]
- Availability and backups: use the wet-nursing and milk-sharing network guide for the source’s two-to-four-donor target and before-birth planning.[2]
What Should Not Automatically End the Conversation
The current book says direct nursing is best, but expressed milk remains useful when direct nursing is not workable. It also says even one breastfeeding session per day can help a bottle-fed baby. The expanded book likewise says a small or occasional amount of human milk matters when formula is used.[1][2]
That means an occasional donor, expressed milk, or a donor who can help with only part of the baby’s needs is not automatically dismissed. The source still applies the health screen to the woman providing that milk.[1][2]
The GAPS chapter emphasizes the immune cells and probiotic microbes in living milk.[1] Their presence does not make every shared milk supply free of infectious risk. FDA guidance calls for a screened source and careful collection, processing, and storage.[6]
Direct Nursing and Expressed Milk
Campbell-McBride ranks direct feeding at the donor’s breast first. Pumping, refrigeration, and reheating reduce some benefit, but the current book still calls that milk preferable to formula. It also says not to microwave donor milk.[1]
Agree on the details before the first feeding: where direct nursing would happen, whether milk will be expressed, who transports it, and how it will be stored and warmed. Ask the baby’s care team for handling instructions that fit the baby’s age and health, especially if the baby is premature or ill.[6]
The Single-Feeding and Vaccination Window
In its vaccination section, the 2020 book says a baby should be breastfed during vaccinations and tells the family to find a healthy local wet nurse when the mother cannot breastfeed. That makes the same health qualification relevant even when the arrangement is one planned feeding rather than an ongoing milk supply.[3]
This is a narrow application of the wet-nurse screen. It does not add a different donor standard or a separate list of vaccination-window criteria.[3][1]
When a Mother Is Evaluating Her Own Milk
The current book also discusses severe situations in which an exclusively breastfed baby is ill and the mother’s own health and milk are part of the pattern.[1] That is different from screening a volunteer donor. The maternal-gut and breast-milk guide keeps the severe examples, proposed mechanism, Vitamin A FAQ route, and exact limits together.
A First-Conversation Checklist
- Ask how she describes her current health.
- List medicines, herbal products, and supplements for a breastfeeding-compatibility review.
- Arrange medical review of the donor’s health and infectious screening, including relevant substance and tobacco history.
- Ask how her own baby is doing and whether the baby is healthy and thriving.
- Decide whether the arrangement is direct nursing, expressed milk, or both.
- Discuss availability, location, milk transfer, and backup coverage, including how expressed milk will be handled.
- Keep diet questions on the separate donor-food route.
Ask these questions plainly and respectfully, and keep the answers together for the medical review. That gives you and the donor a clear starting point before you work out schedules and milk transfer.
What This Looked Like in Our Family
I have nursed for almost six years straight, often eating the same meals I cooked for the rest of my family. Feeding myself and the baby was part of an already full day.[4] That experience is why I would put names, questions, and practical help in place before a feeding gap became urgent.
A short written plan can keep an important detail from getting lost: who is available, which screening questions are still open, and who to call if the first arrangement falls through. My nursing-on-GAPS family story explains the postpartum food and household experience behind that advice.
Prepare the Feeding Plan Before Birth
The Preparing for Baby: A GAPS Preconception Plan for Both Parents course brings GAPS preconception and household preparation together. You can find it in my shop’s course catalog.
Frequently Asked Questions
What Is the Primary GAPS Donor Indicator?
Campbell-McBride calls the donor’s healthy, thriving baby the best indicator of her health.[1] Use it as part of the conversation, alongside medical screening; it cannot establish infection status or medication compatibility.[5]
What Does the Expanded Book Add?
It says to look for women without health problems who are not taking medications. The current book keeps health central and adds the thriving-baby indicator.[2][1]
Does the Donor Have to Nurse Directly?
No. Direct nursing is preferred, but expressed donor milk remains the book’s next human-milk route when direct feeding is not workable.[1]
Does the Same Screen Apply to One Feeding?
The vaccination section still calls for a healthy local wet nurse when the mother cannot breastfeed during that window. It does not create a looser standard for a single planned feeding.[3]
