## TLDR

- Soft breasts, no leaking and evening cluster feeding don't mean low supply. Diapers and weight are the real check.
- To build supply: get a feed watched by an IBCLC, feed or pump 8-12 times a day, and use breast compressions.
- Herbs and lactation cookies have weak evidence. A fed baby comes first; any amount of breast milk counts.

## First, is supply actually low?

Many parents worry about supply when it is fine. These are normal and don't mean low milk:
- Soft breasts after the first 6-12 weeks, or no longer leaking.
- Cluster feeding in the evening or during a growth spurt (see the growth spurts guide).
- Short feeds once a baby gets efficient, or pumping only 0.5-2 oz (15-60 mL) in a session.

What does tell you the baby is getting enough:
- Back to birth weight by about 10-14 days, then gaining roughly 5-7 oz (150-200 g) a week in the
  first months.
- At least 6 heavy wet diapers a day after day 5, and yellow stools in the early weeks.
- Swallowing you can hear, and a baby who seems content after most feeds.

## Common reasons supply runs low

- Milk not removed often or well enough: a shallow latch, a sleepy or preterm baby, tongue tie,
  scheduled feeds, long night stretches early on, or bottles replacing feeds without pumping.
- Health factors in the nursing parent: heavy blood loss at birth, retained placenta, thyroid
  problems, PCOS, diabetes, past breast surgery, or breasts with less glandular tissue.
- Medicines and habits: estrogen-containing birth control, some decongestants, and smoking can all
  lower supply.

## Building supply, step by step

1. Get a feed watched. An IBCLC can check latch, transfer and weight, sometimes with a weighed feed.
2. Feed more often: at least 8-12 times in 24 hours, including at night.
3. Use breast compressions: squeeze gently when sucking slows, to keep milk flowing.
4. Switch sides two or three times per feed when the baby gets drowsy.
5. Add milk removal: hand express or pump for 10-15 minutes after some feeds. Hands-on pumping
   (massage and compression while pumping) adds output.
6. Try a power pumping hour once a day for a few days: pump 20 minutes, rest 10, pump 10, rest 10,
   pump 10.
7. Eat and drink to thirst. Extra water doesn't raise supply.

## Supplements, herbs and cookies

The ABM finds the evidence for herbs, teas, lactation foods and prescription galactagogues weak.
They never replace more frequent milk removal. Talk to a clinician before taking anything,
including herbal products. One medicine sometimes used abroad is not approved for this use in
the US because of heart-rhythm concerns.

## When you need to supplement

A fed baby comes first. Use your own expressed milk first, then pasteurized donor milk or formula,
and protect supply by pumping when the baby gets a supplement. A supplementer at the breast lets
the baby nurse while getting extra. See the combination feeding guide and the donor milk guide.

## Feelings matter too

Low supply can bring grief and guilt. Any amount of breast milk counts, and combination feeding is
a full, valid plan, including for adoptive and non-birthing parents inducing lactation.

## When to check in

- See an IBCLC within a few days if feeds hurt, the baby seems hungry after most feeds, or you plan
  to boost supply.
- Ask the pediatrician for a weight check if wet diapers drop, the baby isn't back to birth weight
  by 2 weeks, or seems too sleepy to feed.
- Mention thyroid symptoms, heavy postpartum bleeding or past breast surgery to your own clinician.
