Feeding is working when the child is safely nourished and the plan is sustainable for the family. Confirm infant nutrition, supplements, allergen timing, and reaction plans with your clinician.
Draws on Chapter 4, Chapter 5, and Chapter 12.

The feeding decision#

Option	Evidence-based framing
Breastfeeding	Modest short-term benefits — fewer GI infections, less eczema, probably fewer ear infections — plus a likely meaningful maternal breast-cancer reduction (20–30%). The dramatic long-term child claims are not supported
Formula	Nutritionally complete and valid where safe formula and clean water are reliable. No compelling evidence of major long-term harm
Combination	A practical middle path. Supplementing is not evidence that breastfeeding has failed
Exclusive pumping	Valid, and a real feeding method — but time- and cleaning-intensive, and pump output varies enormously between people

What doesn't hold up: IQ, obesity, allergies, asthma, height, blood pressure, cavities, postpartum depression, "free birth control." Meaningful weight loss for mom is about 1.4 lb more at six months, which is to say: no.

Why the claims are inflated: in the US, women who breastfeed are on average richer and more educated, and those things independently predict better child outcomes. Sibling comparisons and randomized evidence — which strip that out — consistently shrink the benefits.

Include in your decision: pain, time, sleep, work, mental health, cost, enjoyment, and preference. Feeding method is not a measure of commitment, and guilt has no evidence base and a real cost.

Breastfeeding troubleshooting#

Problem	What to check	Get help when
Pain	Latch, positioning, nipple damage, yeast infection, the baby's oral function	Pain continues through a whole feed, persists past a couple of weeks, or suddenly worsens. Fever plus a red swollen area is mastitis — needs treatment
Supply concern	Weight trend, wet diapers, audible swallowing, observed transfer	The baby gains poorly, urinates less, or is hard to wake. Pump output is not a diagnosis
Delayed milk	Common — about a quarter of women take longer than 3 days, and 35% of first-time mothers	Hydration and weight determine whether supplementation is needed
Low pump output	Flange fit and pump condition before assuming a biological problem	Output is affecting the baby's intake or your work plan
Oversupply / engorgement	Remove enough milk for comfort, not full emptying — full emptying feeds the loop	Fever, a red painful area, or flu-like symptoms

Myths worth dropping:

"Nipple confusion." Randomized trials found no effect from pacifiers (~80% still breastfeeding at 3 months in both arms), and a trial comparing bottle vs. cup supplementation found no difference either
"A good latch doesn't hurt." For many women early breastfeeding hurts regardless. You can't use pain as your latch diagnostic
Supply boosters. Fenugreek, teas, cookies, extra hydration: weak or mixed evidence. Beer slightly reduces supply
Tongue tie. Release has better evidence for reducing maternal pain than for reliably improving feeding. Base it on a functional assessment, not appearance

Reassuring: severe nipple trauma — bleeding, open sores — resolved or became manageable within about two weeks for most women in trials, regardless of treatment.

Diet, alcohol, and medication while nursing#

Only medical food restriction: high-mercury fish. Sushi, unpasteurized cheese, rare steak, deli meat, cauliflower, tap water — all fine
Alcohol: milk concentration tracks blood concentration and falls with it. Pumping does not speed clearance, so there is no need to pump and dump. If being cautious, wait about two hours per drink
Caffeine: fine for most; some babies are genuinely sensitive
Medication: check LactMed or ask a clinician rather than stopping needed treatment. Antidepressants are compatible with nursing — sertraline and paroxetine transfer least. Opioids including codeine are now generally advised against

Starting solids#

Readiness#

Can sit with appropriate support and control head and neck
Swallows food rather than consistently pushing it out
Pediatrician agrees on timing, particularly with prematurity or growth concerns

Allergens — the important part#

The strongest finding in this whole area: early, regular peanut exposure cut peanut allergy from about 17% to 3% by age five in the high-risk group studied. This reversed decades of "delay the allergens" advice.

Discuss timing with the pediatrician, especially with severe eczema or an existing allergy — high-risk infants may need testing or supervised introduction
Use an age-safe form: thinned smooth nut butter or peanut powder, well-cooked egg, yogurt. Never whole nuts or stiff spoonfuls
One new allergen at a time, small amount, when the child is well and you can watch
Know the reaction plan before you start. Breathing trouble or a severe reaction is an emergency
If tolerated, keep it in regular rotation. This is the part that does the work — a single taste is not the intervention that was tested

Food safety#

AVOID: whole nuts, whole grapes, hard candy, and other choking hazards. Cut round foods lengthwise, not into coins
AVOID: honey before age one
AVOID: cow's milk as the primary drink during infancy — dairy foods like yogurt are a different question and are fine
AVOID: sugar-sweetened drinks; whole fruit beats juice
Learn choking-safe preparation and infant first aid/CPR before starting solids

Pickiness#

Offer unfamiliar foods repeatedly. Acceptance can take 10 or more exposures, so giving up after three is giving up a third of the way in
Keep pressure, bargaining, and threats out of the meal. They raise the stakes and make refusal worth something
The division of responsibility: parents decide what, when, and where. The child decides whether and how much — unless a clinician has set a specific feeding plan
Growth faltering, pain, choking, very restricted intake, or nutritional concern belongs with the clinician
