Relactation and Induced Lactation

Two different things with the same mechanism

La Leche League GB defines them cleanly. Relactation is "making milk again after stopping breastfeeding." Induced lactation is "starting to make milk without having been pregnant."

Both work through the same route: frequent stimulation of the nipple and removal of whatever is there tells the body to produce prolactin and, over time, to make milk. Pregnancy is the usual way that process starts, but it is not the only way.

People arrive here for many reasons — a hospital admission that interrupted feeding, an early stop that was regretted, a baby who could not latch and now can, adoption, surrogacy, fostering, or a baby who cannot tolerate formula. The method is broadly the same; the expectations differ.

What determines how much milk you get

La Leche League GB is refreshingly specific about the variables. If you birthed your baby, started off fully breastfeeding, and the gap since you stopped has been short, you have "a very good chance of recovering most or even all of your milk production."

The other end of the range is stated just as plainly: "If the gap has been longer, you had a low milk supply from the start, or you're inducing lactation without having been pregnant, you might expect to make less milk."

Your baby's age matters too. Younger babies are generally more willing to keep trying at a breast that yields little, and the reflexes that drive latching are strongest in the early weeks.

The timeline, honestly

La Leche League GB gives the range: "It can take anything from a few days to a few weeks to be able to express a few drops of milk, and a few weeks more before you are making as much milk as you can make."

The most demoralising phase is the first stretch, when you are expressing eight or more times a day for nothing visible. Knowing in advance that this phase exists — and that it can last a couple of weeks — is most of what gets people through it.

How often, and what to do

Frequency is the whole game. Where you are building supply before a baby arrives, La Leche League GB's target is to "aim to express at least 8 times each 24 hours." Once milk is flowing, the guidance shifts to finding "the minimum number of times you need to express each day to get your full volumes" and then expressing at least that often.

Include a session in the overnight window if you can, because prolactin peaks then. Combine hand expression with a pump rather than relying on the pump alone. And put your baby to the breast as often as they will accept it, even when there is nothing there — direct suckling is a stronger signal than any machine.

Skin-to-skin contact is not decoration here. It raises prolactin, encourages a baby to root and latch, and is one of the few interventions with no downside.

Getting a baby back to the breast

Many babies who have been bottle-fed for weeks will not simply switch. Approaches that tend to work: offering the breast when your baby is sleepy or half asleep rather than very hungry, feeding in a warm bath, using laid-back positions, and starting a bottle feed then switching mid-feed. Never force a baby onto the breast — an aversion is much harder to undo than a slow start.

Supplementers

An at-breast supplementer — a fine tube taped alongside the nipple, running from a container of expressed milk or formula — lets your baby feed at the breast while getting what they need. La Leche League GB describes them as enabling you to give "extra milk (expressed milk or formula) whilst nursing at the breast", and notes they work well for parents with "a partial milk supply who want to feed at the breast."

They solve the central problem of relactation: a baby who will not stay at a breast that gives nothing. They are fiddly, and worth learning with someone who has used one.

Galactagogues, and the caution that comes with them

Herbs and medicines used to increase supply are called galactagogues, and they are the part of relactation with the most noise around it and the least certainty behind it.

La Leche League GB's position is the one to follow: "Evidence for these approaches is limited, and they are not suitable for everyone. If you are interested in taking medications or herbs, you will need to work with your healthcare provider and, ideally, a breastfeeding specialist such as an IBCLC."

We do not give medication advice on this site and will not name doses. Prescription galactagogues have real cardiac and psychiatric contraindications and are not available or recommended everywhere. Ask a pharmacist, your GP, or a specialist medicines-in-lactation service before taking anything, including herbal preparations, which interact with medicines and are not risk-free simply because they are sold without a prescription.

The World Health Organization's review of relactation experience remains the standard reference for the practice internationally, and the Academy of Breastfeeding Medicine publishes clinical protocols that clinicians use in this area.

Redefining what counts as working

La Leche League GB's framing deserves quoting: "Success does not have to mean a full milk supply." It adds that "whatever the outcome, you can still have a warm, close relationship with your baby."

Partial supply is the most common outcome of relactation, and a baby who takes some breast milk and some formula at the breast is a good result, not a half-failure. Set the target as "some milk and feeding at the breast" rather than "exclusive breastfeeding", and you are far more likely to reach it.

When to get help

Ask a breastfeeding specialist, ideally an IBCLC, if:

• You are starting relactation — get a plan before you start rather than after two frustrating weeks.
• Your baby is refusing the breast entirely.
• You want to use a supplementer.
• You are considering herbs or medication to increase supply.
• Your baby's weight gain or nappy output changes while you reduce supplements.

Where to get real help

In the UK the National Breastfeeding Helpline is 0300 100 0212, run by the Breastfeeding Network and the Association of Breastfeeding Mothers, and open every day of the year. The Association of Breastfeeding Mothers publishes a dedicated relactation guide. La Leche League GB runs local groups and a helpline. In Ireland the HSE offers an "Ask our breastfeeding expert" live chat and email service.
