Your Breasts Stopped Feeling Full. That Is Usually Not a Supply Drop.

Soft, floppy breasts at six months are not the warning you think they are. The Royal Berkshire NHS Foundation Trust's infant feeding guidance states that later on, your breasts may begin to feel less "full" or softer, but this does not mean you have less milk — it usually indicates a balanced supply and demand and efficient milk removal by the baby.

That is the headline, and for most mothers the whole answer. It is still worth knowing why, because the reassurance only holds if you also run the checks that do measure your baby's intake. Your chest is not one of them. Neither is your pump.

Not medical advice — talk to your paediatrician or an IBCLC lactation consultant about your own baby.

Why the fullness went away

For the first stretch, your breasts were running ahead of your baby — holding a cushion of stored milk between feeds, which is what that heavy, tight feeling was. Cregan and Hartmann, reviewing computerised breast measurement in the Journal of Human Lactation, concluded that the interaction between storage capacity, degree of fullness and frequency of milk removal plays a significant role in short-term milk synthesis, and that a breastfeeding mother can take comfort in the individuality of her own breast development and feeding pattern, uniquely adapted to the physiology of her breasts and the requirements of her infant. If you have always described yourself as a "just-enougher", that is the sentence to sit with.

Once that loop is tuned, the cushion stops being necessary. Daly, Owens and Hartmann, measuring breast volume before and after every feed across twenty-four hours in Experimental Physiology, found that infants rarely emptied the breasts of available milk — about seventy-six per cent on average — and that within a mother, a breast's storage capacity tracked the demand for milk from that breast. Production follows removal. The breast is not a tank that has run low; it is a tap that has learned your baby's order.

Your timing is not odd, either. The softening is often noticed earlier, in the first few months. But the measured change lands about where you are standing: Kent and colleagues, tracking breast volume and milk production through extended lactation, found that the extra breast tissue built in pregnancy was maintained for the first six months of lactation and decreased after that — and that at fifteen months, milk production from each breast was still substantial even though the breasts had returned to their pre-conception size.

Read that twice: breasts back to their pre-pregnancy size, still making plenty of milk. Size and fullness are simply not output — the same reason breast size does not predict supply.

One thing to hold separately: a change you noticed over a handful of days is more likely to be a change in how your baby is feeding than in what you make. If it arrived alongside him sleeping longer, that has its own explanation. If it came with other changes you can point to, declining supply in established breastfeeding is the piece for that.

What actually tells you he is getting enough

Sensation is not measurement, and a pump reports only what it got out of you on that occasion. The indicators that count are dull, external and countable.

• Nappies. The NHS counts at least six heavy, wet nappies every twenty-four hours, from day five onwards, among the signs a baby is getting enough milk.
• Weight along his chart. The American Academy of Pediatrics calls inadequate weight gain one of the strongest signs that a baby is not getting enough milk — which is why a weigh-in, plotted on his growth chart, answers your question and a hand on your breast cannot.
• Behaviour. He comes off the breast himself, seems content after most feeds, and looks healthy and alert when he is awake — all on the same NHS list.
• Feeding pattern. He still asks for the breast through the day, and you can still hear him swallowing.

Get him weighed, rather than reasoning further, if his gain has flattened or fallen away from his line, if the wet nappies have thinned out or the urine looks dark, if he is listless or hard to rouse, or if he stays hungry and unsettled after most feeds. NHS Best Start in Life advises that generally the more your baby feeds the more breast milk you produce, and that a mother worried her baby is not getting enough should talk to her midwife, health visitor or a breastfeeding specialist as soon as possible. In India that is your paediatrician or an IBCLC lactation consultant; most urban hospitals have one attached to maternity.

Solids starting is not a reason your supply should fall

He plays with the purée more than he eats it. That is the expected track, not a failing appetite. The NHS says that at the beginning, how much your baby eats is less important than getting them used to the idea of eating, and that they will still be getting most of their energy and nutrients from breast milk. The American Academy of Pediatrics is blunter: after the first six months, breast milk continues to provide the great majority of needed nutrients, and those first encounters with food are still practice sessions.

The Indian Academy of Pediatrics' complementary feeding guidance says to start at six completed months with small amounts of food and increase the quantity as the child gets older, while maintaining frequent breastfeeding — frequent breastfeeding is part of the instruction, not a thing the dal-chawal replaces. WHO's guiding principles for complementary feeding are to continue frequent breastfeeding up to two years of age or beyond and to practise responsive feeding, recognising and responding to signs of hunger and fullness. Starting solids covers the first few days.

The pumping question, on its own terms

You want to pump to lift your supply, and you are holding back because he will not drink it from a bottle. Those two facts are far less connected than they feel.

Pumping works through the removal itself — Oxford Health NHS Foundation Trust's infant feeding guidance states that milk supply is established and increased by regular and effective milk removal. The NHS lists boosting your supply among the reasons to express, and including some breast milk once solids start as another. The signal reaches your breast when the milk comes out of it; what happens to it afterwards is a separate decision, and none of the effect depends on him taking it from a teat.

And he need not. The NHS advises introducing a cup or beaker from around six months, using an open cup or a free-flow cup without a valve so he learns to sip. A spoon works as well, and expressed milk stirred into his porridge, khichdi or cereal is still milk he drinks. It also keeps — storing pumped milk covers the fridge and freezer rules.

The harder question is whether you need to pump at all. If the nappies are wet and his weight is tracking his line, nothing above describes a problem to solve, and the individuality Cregan and Hartmann describe is the whole point — your pattern is adapted to your breasts and your baby, not to a target in a bottle. Get him weighed first. Pump after that, if the weighing gives you a reason to.

If you want a bottle in the mix for other reasons, bottle refusal is its own project. And when a relative suggests tablets, read domperidone and milk supply before anyone fills a prescription.

The short version

Soft breasts, a baby gaining along his line, wet nappies, a mother convinced she is only just keeping up — that is a measured, ordinary state of established breastfeeding, the one the extended-lactation measurements were taken in. Check him, not yourself.
