Eating and drinking while breastfeeding

Good news after months of pregnancy food rules: breastfeeding comes with far fewer restrictions. You can largely eat and drink normally — you don’t need a special diet, and most of the “avoid” list from pregnancy no longer applies. Here’s what actually matters.

Eat well, but don’t stress about perfection. Aim for a varied, balanced diet with plenty of vegetables, fruit, wholegrains, protein and dairy (or alternatives) — as much for your own energy and recovery as for your milk. Your body makes good milk even if your diet isn’t perfect, so don’t put pressure on yourself; a run of toast-and-coffee survival days won’t harm your baby.

You don’t need to “eat for two” (or drink gallons). You may feel hungrier while breastfeeding — that’s normal, so eat to your appetite and keep easy snacks handy for those pinned- under-a-feeding-baby moments. For fluids, drink to thirst; there’s no need to force litres of water, though keeping a drink nearby when you feed is a good habit.

The pregnancy food rules relax. The foods you avoided in pregnancy — soft cheeses, deli meats, sushi, rare steak — are generally fine again while breastfeeding, because the listeria concern was about the baby in the womb. Enjoy them. Normal food-hygiene sense still applies, but the special restrictions lift.

Caffeine — fine in moderation. You can have caffeine while breastfeeding; a moderate amount (a couple of cups of coffee a day) is generally considered okay. Large amounts pass into milk and can make some babies unsettled or wakeful, so if your baby seems jittery or isn’t sleeping, try cutting back and see.

Alcohol — plan around feeds. Not drinking is the safest option, but if you choose to drink, do it in moderation and time it around feeds. Alcohol passes into breastmilk at about the level in your blood, and “pumping and dumping” doesn’t speed up clearing it — time does. A common approach is to feed first, then have a drink, and wait a couple of hours per standard drink before the next feed. The ABA has clear guidance worth a look.

Fish and omega-3s. Fish is good for you and your baby’s brain development, so include it — just limit high-mercury fish (like shark/flake, marlin, swordfish) and favour low-mercury options (salmon, sardines, tuna in moderation). The mercury guidance from pregnancy still broadly applies here.

Does what you eat cause wind or fussiness? Usually not. It’s a common worry, but for most babies, foods in your diet (spicy food, garlic, “gassy” veg) don’t cause problems, and you don’t need to cut things out. Don’t eliminate foods from your diet without advice — if you suspect a genuine reaction (for example to dairy, with other symptoms), talk to your GP, child health nurse or a dietitian first rather than restricting unnecessarily.

Keep taking care of you. Your own nourishment matters — you’re recovering from birth and running on broken sleep. Prioritise regular meals, iron-rich foods (your levels may be low after birth), and ask your GP about continuing a supplement if you’re not eating well. Looking after yourself is looking after your baby.

Herbs, supplements and “milk-boosting” foods. You’ll see lactation cookies, teas and herbal galactagogues everywhere. Most are harmless in normal amounts and some people enjoy them, but the evidence they meaningfully boost supply is thin — frequent, effective feeding is what actually drives milk. Check any herbal supplement or medication with your pharmacist or GP before taking it, as a few pass into milk or affect supply.

The bottom line: eat a normal, varied diet to your appetite, drink to thirst, enjoy the foods that were off-limits in pregnancy, keep caffeine moderate, plan any alcohol around feeds, and don’t cut out foods on a hunch. Feed yourself well — your milk, and your energy, will follow. The ABA helpline (1800 686 268) is there for any specific questions.
