Milk Supply 101: What Actually
Affects It, According to an IBCLC
Is it really possible to have "not enough milk"? We asked Eliza at Tender Loving Milk (TLM) to break down what genuinely drives milk supply — and the everyday habits that quietly work against it.
What actually affects milk supply?
Milk supply comes down to two main components: hormonal drive (your body's own condition) and mechanical drive — how frequently and how efficiently milk is removed. Efficiency matters just as much as frequency, which is why something as small as a deep latch or the correct pump flange size can make a real difference to supply.
Is it possible to have "not enough milk," or is that often misunderstood?
Yes, it is possible — but true primary low milk supply is rare, usually linked to specific chronic illnesses or hormonal imbalances. What's far more common is secondary or perceived low supply: topping up with formula when baby isn't actually showing hunger cues, delaying milk removal, or stretching out feeding intervals too soon. The reassuring part is that these situations can usually be corrected by adjusting your body condition and breastfeeding practices.
Most "low supply" worries are secondary, not primary — and secondary issues are usually fixable once the underlying habit is identified.
How can mums increase supply naturally?
Diet, lifestyle, and having enough support to rest and spend time with baby all make a genuine difference. Frequent skin-to-skin contact is one of the simplest, most effective habits to build in — and getting trained lactation help to check milk removal efficiency, whether that's your latch or your pump fit, is often the missing piece.
Silicone Breast Pump & Bottle Top Set 160ml
A gentle, suction-based manual pump that's easy to use for catching let-down on the opposite side — a favourite for supporting supply without added stress.

Reusable Hot & Cold Breast Compress
Designed with an IBCLC, this compress supports comfortable, effective milk removal by easing engorgement and encouraging let-down before feeds or pumping.
Can certain foods or drinks really increase breast milk?
Yes — certain foods are lactogenic in nature, though results vary quite a bit between individuals. Often, it's less about any single "miracle" food and more about simply increasing overall caloric intake and staying well hydrated, which tends to make more of a difference than people expect.
What are some common mistakes that unintentionally reduce milk supply?
Separation from baby, stress over supply itself, poor nutrition, and a lack of support in the postpartum period tend to be the biggest culprits. And two very fixable ones round out the list: a shallow latch, and an incorrectly sized pump flange — both of which quietly reduce how efficiently milk is actually removed.

Tender Nipple Shield (2pcs + Case)
Ultra-thin silicone shield sized S, M and L to support a deeper, more effective latch while sore or healing nipples recover.

i1 Plus Hospital Grade Breast Pump
A quiet, hospital-grade dual pump with a deep, gentle pull — worth pairing with a proper flange fitting check for the most efficient removal.
If something feels off with your supply, the fastest way to find out why is a proper latch and flange-fit check with an IBCLC — not guesswork.
