Low Milk Supply: The Real Signs and How to Increase Your Milk

It is 7 pm, baby fed forty minutes ago and here he is again, rooting against your chest. Your breasts feel soft, almost empty. And someone in the family slips in that “this milk isn't feeding him”. The fear of low milk supply is one of the first reasons for stopping breastfeeding. Yet it often rests on false signs.

The good news: there are simple guides to tell whether baby is drinking enough, and effective steps to increase your milk when it really is too low. Here is how to sort it out.

How does milk production work?

Lactation follows a simple rule: the more the breast is emptied, the more it makes. Each effective feed sends the body the signal to make more milk. Conversely, a breast that stays full for a long time slows its production.

That is why the WHO recommends breastfeeding “as often as the child wants, day and night”. Quebec's INSPQ gives a concrete benchmark: milk should be removed from the breasts at least 8 times in 24 hours, night included, by feeds or, if needed, by expressing.

The first days lay the foundations. If you are there now, our article on getting off to a good start with breastfeeding details the first week, and the one on your milk coming in explains the shift from colostrum to mature milk.

The false signs that worry you needlessly

Several situations wrongly make you think you are short of milk. La Leche League and the INSPQ both cite them.

• Your breasts become soft and stop leaking. After a few weeks, production adjusts to baby's needs: the breasts are no longer tense, without containing less milk.
• Baby feeds very often, for a long time, or asks non-stop on certain evenings. Some infants have a great need to suck, also for reassurance, notes La Leche League. A baby who asks often is not necessarily hungry.
• Baby sleeps little. Again, this is no proof that he lacks milk.
• You barely pump anything. A baby who feeds well generally empties the breast better than a machine, and the INSPQ reminds us that an inefficient device gives small volumes.

The real signs that baby is drinking enough (or not)

Nappies and weight are the most reliable guides. The sources agree on these figures:

Weight matters just as much. A newborn can lose up to 8 to 10% of his birth weight in the first days, according to the American Academy of Pediatrics. He should then gain weight steadily. Our article on the growth chart helps you read these figures with your paediatrician or at the health centre.

Other signs reassure: you can hear baby swallow, his cheeks stay round during the feed, he lets go of the breast himself, he is alert and has good muscle tone between feeds.

The signs that should alert you are the opposite: few wet nappies, dark urine, infrequent stools in the first weeks, a very sleepy baby who asks little, or a weight curve that stalls.

Growth spurts: when baby asks for more for a day or two

Some days, baby seems insatiable. These are often growth spurts: he feeds more to raise your production to match his needs. Naître et grandir places them around 7 to 10 days, 3 to 6 weeks and 3 to 4 months. They usually last a day or two.

The response is simple: follow baby and offer the breast as often as he asks. Giving something else “to settle him” on those days sends the body the opposite message, and production does not keep up.

Why milk can really drop

A true physical insufficiency of milk is rare. La Leche League France put it at 1 to 5% of cases at most, in an old but still-cited report. Most often, production drops because the breasts are not stimulated enough. UNICEF and the INSPQ cite:

• feeds spaced too far apart, at fixed times, too short, or no feed at night;
• an ineffective latch that removes little milk (pain, cracked nipples, a baby who falls asleep quickly);
• regular supplements replacing feeds;
• a restrictive tongue-tie, or a premature or very sleepy baby who feeds weakly: see our article on tongue-tie;
• on the mother's side: breast surgery, certain health problems (thyroid, poorly controlled diabetes, significant anaemia), a haemorrhage at birth, a new pregnancy, the contraceptive pill or certain decongestants;
• tiredness, stress and lack of confidence, which UNICEF also cites.

How to increase your milk, in practice

The main lever remains the frequency and effectiveness of feeds. The recommendations of the NHS, the INSPQ and Naître et grandir converge.

1. Have a feed checked. A midwife, a lactation consultant or a trained paediatrician often spots a latch to correct within minutes. Our guide to breastfeeding positions helps in the meantime.
2. Breastfeed on demand, at least 8 times in 24 hours, night included, and wake a newborn who sleeps too much.
3. Offer both breasts at each feed, and change the starting breast each time. Naître et grandir even advises offering each breast several times again.
4. Keep baby close. Skin-to-skin and sharing a room day and night help you spot his first hunger cues, before the crying.
5. Add an expression of milk after some feeds, once breastfeeding is under way, to stimulate more. Our article on pumping at the right time and the guide to choosing a breast pump help you organise.
6. Hold off on the dummy until breastfeeding is well established, as the NHS advises: every need to suck then counts as stimulation.
7. Rest and delegate. Let the family take over housework, meals and visitors.

What helps you keep up the feeding rhythm

No object makes milk. A good pillow makes frequent feeds more comfortable, a breast pump helps when you need extra stimulation, and a bracelet reminds you which breast to start on.

Helba, sellou, herbal teas: what about plants?

In many Moroccan families, people prepare helba (fenugreek) or drinks “for the milk”. Their effectiveness is not proven, and some plants carry risks. We review this in our article on what a breastfeeding mother eats. No plant and no medication replaces more frequent feeds. Do not take any without medical advice.

And if a supplement is needed?

Sometimes, despite everything, baby does not gain enough weight. The supplement is then decided with the paediatrician, and kept temporary if possible. The INSPQ insists on two priorities: feeding baby enough, and protecting your production by continuing to stimulate the breasts. The milk you express can be given to him with a teaspoon or a cup. Our article on combination feeding explains how to reconcile supplements and lactation.
