What it is

Breastfeeding aversion is a strong negative physical reaction during a feed: skin crawling, itching, restlessness, agitation, sometimes rage, and an overwhelming urge to unlatch your child immediately. Unlike D-MER, which is a brief wave at let-down, aversion lasts through the feed and can build the longer it goes on.

La Leche League GB names it directly and puts it in context: not enjoying breastfeeding all the time, or developing nursing aversion, is very common. It also says something worth repeating — it is a rare mother who enjoys every single moment of feeding, however long she does it for.

When it tends to appear

Feeding while pregnant. One of the most common triggers, and La Leche League GB notes that for some people an aversion is the first sign of pregnancy. Feeding through pregnancy can be genuinely tough and even painful.
Feeding a toddler or older child, particularly one who feeds often, fiddles, pinches or nips.
Around ovulation and periods. LLLGB notes many people find aversion is linked to hormonal changes and that some struggle specifically at those points in the cycle.
Tandem feeding, where feeding two children at once can feel overwhelming.
When you are exhausted, hungry, dehydrated or touched out after a day of being climbed on.

It can also appear with a younger baby and no obvious trigger, which is disorienting but not abnormal.

What it is not

It is not a sign that you do not love your child, that you resent them, or that you are failing at something other people manage. It is not the same as postnatal depression, though the two can coexist. And it is not a character problem to be overcome with more determination — it is a physical response, and the shame that usually comes with it is by far the worst part.

What helps

The most important principle in La Leche League GB's guidance is that breastfeeding is a relationship between two people, and if a part of it is not working, it is fine to change it. You are one of the two people whose needs count.

Set a limit on the feed. LLLGB suggests counting up to or down from ten, or singing a nursery rhyme, so there is a predictable end your child can learn.
Reduce the number of feeds by distraction rather than refusal — a snack, going outside, a change of activity at the times feeds usually happen.
Insist on nursing manners. No pinching, no acrobatics, no feeding while standing on you. A "fiddle" necklace gives busy hands somewhere else to go.
Say "not now, but later", and mean it. Deferring is easier for a toddler than refusing.
Keep hydrated, fed and rested. LLLGB lists this specifically for aversion in pregnancy, and the Australian Breastfeeding Association's guidance on self-care makes the same point. Aversion is reliably worse when you are running on empty.
Move. Wiggling your feet, stroking your own arm, or getting up as soon as the feed ends discharges some of the agitation.
Change position so you are not pinned, or feed side-lying so you can move.
Tell someone. The shame is worse than the sensation, and the relief of hearing that other people feel this is substantial.

Partial weaning is a real option

The choice is not between enduring every feed and stopping entirely. Many people find aversion is tied to particular feeds — often night feeds, or the long morning one — and dropping just those changes everything. Night weaning while continuing to feed in the day, or feeding only at bedtime, are common and workable arrangements. La Leche League GB's guidance on thinking about weaning and on feeding beyond a year both treat this as a normal thing to plan for rather than a defeat.

If you decide to stop

That is a legitimate decision, and it does not need to be justified to anyone. Wean gradually where you can — dropping one feed every few days protects you from engorgement and mastitis, and gives your child time to adjust. Expect some mixed feelings; relief and sadness very often turn up together.

When to get more help

The aversion comes with rage that frightens you, or you are worried about how you might react.
Low mood, anxiety or detachment persists between feeds and through the day.
Feeding is triggering memories or physical responses connected to past trauma or abuse. This is more common than it is talked about, and it deserves specialist support rather than self-management.
You are dreading every feed and cannot see a way through.

Speak to your GP, health visitor or public health nurse, or call the National Breastfeeding Helpline on 0300 100 0212. Feeling this way is not a reason to be judged, and telling someone is the step that usually changes it.

Feeding two children at once

Tandem feeding is where aversion most often becomes unmanageable, because there is no gap between feeds and no way to defer. Feeding the children separately rather than together, prioritising the younger one, setting a firm limit on the older child's feeds, and dropping some of them entirely are all normal adjustments. La Leche League GB's position is that the aim is to help you meet your own goals and find a balance that works for your family, which includes deciding that tandem feeding is not it.

Keeping track of when it happens

Noting which feeds trigger it for a week or two is more useful than it sounds. Most people find a pattern — a particular time of day, a particular week of the month, always when they are hungry, always the third feed in a row. Once the pattern is visible, the change usually suggests itself, and it is generally smaller than stopping altogether.
