Do I have enough milk? — what to know about supply

"I must not have enough milk." This is the sentence I hear most often on the phone — and most often it is not true. Not because the worry is unfounded, but because the signs mothers watch for mean something different from what they assume.

What does NOT tell you your supply is low

• Your breasts feel soft. Around six weeks supply regulates: the breast stops storing surplus and makes milk to match the feeding. That is maturing, not drying up.
• You cannot feel let-down. Many never do, and others stop feeling it after a few months. It means nothing.
• You pump very little. A pump is not a measuring device. A baby drains more effectively than any machine, and pump output varies with time of day, stress and flange size.
• The baby feeds often. Breast milk digests quickly. Eight to twelve feeds a day is not a lot — it is the norm. Evening cluster feeding (hourly or more) typically appears around 3, 6 and 12 weeks and lasts a few days.
• Feeds have got shorter. A three-month-old often takes in seven minutes what needed half an hour as a newborn. That is skill.
• The baby cries after a feed. Crying has many causes: tiredness, overstimulation, tummy discomfort, a need to suck. It is not always hunger.

What actually tells you

There are two reliable measures, and both show on the baby, not on you:

• Nappies: after the first week, 5–6 well-soaked nappies a day and regular stools.
• Weight gain: weekly, on the same scales. Typically 150–200 grams a week in the first three months.

If those two are fine, you have enough milk — whatever your breasts feel like or the pump suggests.

When supply genuinely is low

It happens, and there are reasons. The most common:

• infrequent or scheduled feeds, with long night gaps
• a poor latch — plenty of sucking, little drainage
• early, routine formula top-ups or dummy use
• a significant illness, surgery, or heavy blood loss at birth
• thyroid problems, PCOS, retained placental fragments
• certain medicines, including some contraceptives and decongestants

Most of these are treatable, but not at the "eat more porridge" level — they are worth investigating.

What genuinely increases supply

Milk production works on supply and demand: drainage calls up production.

• Feed more often, at night too — prolactin is highest in the early hours.
• Offer both breasts, and if the baby falls asleep, switch sides ("switch nursing").
• Use breast compression: gently squeeze the breast during a feed to restart the flow.
• If you supplement, pump for every feed you replace.
• Skin to skin, plenty of it. This is not a mystical suggestion: it measurably raises the hormones that drive milk production.
• Rest where you can, and eat and drink properly. That alone will not raise supply, but exhaustion lowers it.

Herbal teas and capsules have inconsistent effects and never replace more frequent drainage. If medication is suggested, discuss it with a doctor.

If you are already supplementing

Formula is not irreversible. I have worked with many mothers on gradually reducing daily top-ups while feeding and pumping bring their own supply back up. It takes a plan and a few weeks — but it works.

What we do together

We look at how much milk actually transfers during a feed, go through your day, and find where supply is being lost. Usually nothing dramatic is needed: more frequent drainage, a better latch, and a clear plan for what to measure and when.
