The GAPS failure-to-thrive feeding route begins with a very small amount of warm homemade meat stock and a tolerated homemade probiotic food before breastfeeding. The amount increases gradually. Breast milk continues as the top-up after the food attempt, and the attempt stops when the baby is distressed.[1][2]
This passage concerns an infant who does well on breast milk, feels unwell after solid food, refuses it, and then does not gain enough weight or begins losing weight. Failure to thrive and picky eating are different concerns. The sequence below explains the feeding approach described in the GAPS sources.
Poor weight gain or weight loss needs prompt assessment by your baby’s clinician. This article explains a dietary approach described in GAPS; it is not a diagnosis or an individualized feeding plan. Do not delay assessment while trying food changes.[6]
Why Solids May Be Refused
In the pattern Campbell-McBride describes, partial digestion makes solid food uncomfortable and teaches the infant to refuse it.[1][2]
How Failure to Thrive Enters the Picture
The chapter connects difficulty establishing solids with inadequate weight gain or weight loss once breast milk alone no longer meets the baby’s needs. That is the context for its failure-to-thrive feeding sequence.[1][2]
Leave Grain-Based Weaning Foods Out
The failure-to-thrive section calls typical grain-based weaning foods completely inappropriate for the babies described here and says not to give them. The route begins with homemade foods from the New Baby sequence instead of rice cereal, oat cereal, infant biscuits or other grain-based first foods.[1][2]
The First-Food Sequence
| Step | What the Source Says | What to Record |
|---|---|---|
| Prepare the first food | Warm homemade meat stock with a small amount of tolerated homemade probiotic food | The exact stock and probiotic food used |
| Begin small | Start with about 1 to 2 teaspoons before breastfeeding | Amount offered and amount taken |
| Top up | Offer breast milk after the stock-and-probiotic attempt | Time of food attempt and nursing |
| Repeat calmly | Use frequent offers when the baby and mother are calm | Time, mood and response |
| Stop the demand | If the baby is distressed, breastfeed for comfort without requiring food first | Why the food attempt was paused |
| Progress | Increase gradually, then move into the foods in the New Baby schedule | Each new food, prepared form and response |
Use Meat Stock, Not Bone Broth
The opening food is meat stock made from raw meaty bones, joints, skin, connective tissue, fat and meat. In Gut and Physiology Syndrome, the stock simmers for 2.5 to 4 hours. Fish stock takes about 1 to 1.5 hours. The same book says the GAPS Nutritional Protocol focuses on meat stock and holds bone broth for at least the first year, and longer for some people.[3]
Commercial stock granules and bouillon cubes do not replace it. Use the GAPS chicken meat stock recipe for the full preparation. For this infant serving, keep the baby’s prescribed amount and leave out ingredients not yet introduced. After straining, cool the stock promptly in an ice bath, then refrigerate up to two days or freeze small portions.[7]
Choose a Tolerated Homemade Probiotic Food
Dr. Campbell-McBride’s official failure-to-thrive guide specifies warm homemade meat stock mixed with homemade yogurt.[2] The expanded German book uses the broader term “probiotic food.”[1] These are different descriptions; the official guide does not name a substitute for yogurt. If dairy is a problem, agree on the baby’s feeding plan rather than assuming another ferment is the same treatment.
Homemade yogurt is fermented for at least 24 hours. The 2020 book calls that preparation lactose-free, while the official GAPS FAQ explains that fermentation varies and some lactose may remain. It gives 36 hours or longer as an option for especially sensitive people.[3][4]
Use the Baby GAPS wrist-test guide before introducing the probiotic food. If yogurt is not tolerated, do not replace it with finished commercial yogurt. Keep the preparation homemade and use the tolerated form permitted by the GAPS sequence. A clear wrist spot does not rule out food allergy. Follow the baby’s allergy plan.[8]
How Often the Sources Describe Offering Food
The official failure-to-thrive guide describes small offers every hour. The expanded German book gives an older interval of one to two hours.[2][1] Both retain calm timing and breastfeeding for comfort when a baby is distressed. For the current official description, use the hourly wording; the baby’s actual feeding schedule still needs to meet the individual growth and nutrition plan.[6]
Choose a time when you and the baby are calm. Keep the offer small and achievable, and stop the attempt if the baby becomes upset. Needed milk is not something to withhold to make an infant accept solids.[6]
Breastfeeding Comes After the Food Attempt
In this specific sequence, the baby takes some stock with probiotic food from a bottle or beaker, then breastfeeds as a reward or top-up. The general New Baby chapter also allows stock from a spoon. That describes the book’s order for a calm attempt, with nursing immediately available for comfort. It does not justify delaying needed milk or leaving a baby without adequate intake.[6][1][2]
Breastfeeding continues through the gradual food introduction in the book’s sequence. For the infants described in this section, Campbell-McBride recommends continuing breastfeeding until at least 18–24 months of age.[1][2]
Move Into the New Baby Schedule
Once the baby is taking a useful amount of stock with probiotic food, add the other foods from the New Baby chapter gradually and in its stated order. This is not a separate failure-to-thrive diet with a new list. It is the Baby GAPS sequence entered through a more deliberate first-food route.[1][3]
Use the complete Baby GAPS first-food guide for the week-by-week progression. It shows which foods and textures come next, so you can keep the whole sequence in view.
Where No-Plant GAPS Fits
In Gut and Physiology Syndrome, Campbell-McBride directly lists babies with failure to thrive and FPIES among the groups for whom she recommends considering No-Plant GAPS. She advises working with a Certified GAPS Practitioner, changing gradually from the previous diet, and continuing breastfeeding while the mother follows Full GAPS. Her failure-to-thrive entry also points readers to the FPIES discussion.[3]
The official diet-spectrum page describes No-Plant as an extreme approach after unresolved symptoms on Intro or Full GAPS.[5] That broader description does not erase the 2020 book’s specific infant indications. It remains an individual feeding decision with growth and nutritional intake assessed, not an automatic response to a difficult meal.[6]
What to Write Down
With six children in our household, I would keep a short written record for a routine with repeated steps. For this route, I would keep the stock, measuring spoon and written record together. Write down the time, amount offered, amount taken, probiotic form, nursing top-up and response. Keeping those details together makes the next small offer easier to plan.

Frequently Asked Questions
What Food Comes First?
Warm homemade meat stock with a small amount of tolerated homemade probiotic food. The official page names homemade yogurt, while the expanded book uses the broader probiotic-food wording.[1][2]
How Much Stock Comes First?
Begin with about 1 to 2 teaspoons before breastfeeding and increase the amount gradually.[1]
Does Breastfeeding Stop?
No. Breastfeeding continues. The book describes a small food attempt before nursing when the baby is calm, and immediate comfort nursing when distressed. Do not withhold needed milk; follow the baby’s feeding and growth plan.[1][6]
Can Bone Broth Replace Meat Stock?
No. The opening food is short-cooked meat stock. The 2020 book holds bone broth for at least the first year on GAPS, and longer for some people.[3]
Is No-Plant GAPS the Next Step for Every Baby?
No. The 2020 book specifically includes babies with FPIES and failure to thrive and recommends practitioner guidance. The diet-spectrum page describes the broader severe-case use after Intro and Full GAPS have not resolved symptoms. Neither makes it the next step for every baby who refuses a food.[3][5]
For the wider growth question, read the failure-to-thrive overview, the GAPS explanation of food refusal and malabsorption, and the growth and feeding record. The extended-breastfeeding guide covers the separate duration discussion.
