Breastfeeding Basics: What to Expect in the Early Weeks

Breastfeeding is one of those things that looks simple from the outside and is considerably more complicated from the inside. The image most people carry into it — baby latches on, feeds contentedly, everyone rests — bears almost no resemblance to what the first two weeks actually look like for most women.

This isn't because something has gone wrong. It's because breastfeeding is a skill that both you and your baby are learning simultaneously, under conditions of significant sleep deprivation, while your hormones are doing something dramatic. The early weeks are genuinely hard for most people. Knowing what's normal, what's a problem worth addressing, and who to call when you need help makes navigating them considerably more manageable.

Before your milk comes in: colostrum

In the first two to four days after birth, your breasts produce colostrum rather than mature milk. Colostrum is a thick, concentrated fluid that is nutritionally dense and rich in antibodies. It is produced in very small quantities — often just a few millilitres per feed — which is appropriate because your newborn's stomach is roughly the size of a marble in the first days of life.

Many women worry in those early days that they don't have enough milk because they can't see or measure what their baby is getting. Colostrum production is normal and adequate even when it feels invisible. The cues that feeding is working are your baby's nappy output — at least one wet nappy on day one, increasing by one per day — and your baby settling after feeds even briefly.

Colostrum transitions to mature milk, often called the milk coming in, between days two and five after birth. This transition is frequently accompanied by engorgement, which can be abrupt and uncomfortable.

When your milk comes in

Milk coming in is one of the more physically surprising events of the early postpartum period, particularly for first-time mothers. The breasts become significantly larger, harder, and often tender very quickly — sometimes within a few hours.

Mild to moderate engorgement in the first days after milk comes in is normal and usually resolves within 24 to 48 hours as supply begins to regulate to your baby's demand. Feeding frequently — or expressing a small amount if your baby is unable to latch onto a very full breast — is the most effective way to manage engorgement.

Severe engorgement where the breasts become rock hard and the nipple flattens, making it impossible for the baby to latch, is a situation worth getting support for promptly. A lactation consultant or your child and family health nurse can help with techniques to soften the areola before feeding and make latching possible again.

The latch: why it matters and what it should feel like

The latch is the single most important technical element of breastfeeding and the source of most early difficulties. A good latch is one where your baby takes a large mouthful of breast tissue — not just the nipple — into their mouth. Their lips should be flanged outward, their chin pressed into the breast, and their nose free to breathe.

A correct latch should not be painful beyond the first few seconds of each feed. Initial discomfort as the baby attaches, particularly in the first week while your nipples are tenderising, is normal. Pain that persists throughout the entire feed, nipples that emerge from your baby's mouth looking pinched, creased, or misshapen, and cracked or bleeding nipples are all signs the latch needs attention rather than signs that breastfeeding isn't working.

Getting latch assessed by a lactation consultant, your midwife, or the Australian Breastfeeding Association is the most efficient way to identify and fix latch issues. Many problems that cause women to stop breastfeeding before they wanted to are correctable with specific, targeted guidance.

How often newborns feed and what that looks like

Newborn feeding in the early weeks operates on demand rather than a schedule. This means feeding whenever your baby shows hunger cues: rooting, bringing hands to mouth, turning the head side to side, increased alertness and agitation. Crying is a late hunger cue — a baby who is already crying from hunger is harder to latch than one who is just beginning to signal.

In the first weeks, expect eight to twelve feeds per day, which averages out to a feed every two to three hours around the clock. Some feeds will be long and some will be short. Some babies cluster feed, meaning they feed very frequently for several hours, often in the evening. This is normal behaviour and is not a sign that you don't have enough milk.

Cluster feeding is exhausting and frequently misread as inadequate supply. It is actually your baby stimulating your supply in preparation for a period of faster growth. The best response to cluster feeding is to keep feeding, stay hydrated, eat enough, and let someone else handle everything else while it's happening.

Supply: understanding how it works

Breast milk operates on a supply and demand system. The more milk is removed from the breast, the more is produced. The less that is removed, the less is produced. This is why feeding frequently in the early weeks is the most important thing you can do to establish and maintain supply.

Concerns about low supply are among the most common reasons women stop breastfeeding before they intended to. True low supply exists but is less common than the anxiety around it. The reliable indicators that supply is adequate are your baby's nappy output — six or more wet nappies per day from day six, with regular bowel movements — and weight gain that returns to birth weight by two weeks.

What doesn't reliably indicate supply: how your breasts feel between feeds, whether you can express a specific volume, how long your baby feeds for, or how often your baby wants to feed. These are frequently misinterpreted as supply problems but are usually not.

If you have genuine concerns about supply, a weighted feed assessment with a lactation consultant provides actual data rather than anxiety-driven guesswork.

Common challenges in the early weeks and what to do about them

Nipple pain and cracking

Some nipple tenderness in the first week is normal. Lanolin cream applied after feeds and allowing nipples to air dry helps manage discomfort. Pain that is severe, persists throughout the whole feed rather than easing after the initial latch, or produces cracked and bleeding nipples is a sign the latch needs assessment rather than something to simply endure.

Blocked ducts

A blocked milk duct feels like a firm, tender lump in the breast. It develops when milk isn't draining properly from one area. Frequent feeding or expressing, gentle massage of the affected area toward the nipple during feeds, and ensuring your bra isn't too tight are the first steps. Most blocked ducts resolve within 24 to 48 hours with these measures.

Mastitis

Mastitis is an inflammation of the breast tissue that can develop from a blocked duct or bacteria entering through cracked nipple skin. Symptoms include a painful, red, swollen area of the breast, often accompanied by flu-like symptoms including fever, chills, and body aches. Contact your GP promptly if you develop these symptoms — mastitis is treated with antibiotics and continuing to feed or express from the affected breast speeds recovery. Stopping feeding does not help and can make things worse.

Nipple thrush

Nipple thrush is a fungal infection that produces a distinctive burning or shooting pain in the nipple or breast, often between feeds. Your baby may also have white patches in their mouth. Both you and your baby need treatment simultaneously. Contact your GP if you suspect thrush.

Tongue and lip tie

A tongue tie is a restriction of the frenulum, the small piece of tissue under the tongue, that limits the tongue's range of movement and affects a baby's ability to latch effectively. Symptoms include nipple pain and damage, poor weight gain, clicking sounds during feeds, and a baby who slips off the breast frequently. Tongue tie assessment and, where indicated, a minor procedure called a frenulotomy can make a significant difference to feeding outcomes. Ask your midwife, GP, or lactation consultant for assessment if you suspect this may be a factor.

Formula feeding and combination feeding

Breastfeeding is not the right fit for every mother and every baby, and formula feeding provides complete nutrition for babies who are not breastfed. If you have made the decision to formula feed, or the decision has been made for you by circumstances, that is a legitimate choice that deserves support rather than judgment.

Combination feeding, using both breast milk and formula, is also a valid approach that many Australian families use for a range of reasons. If you want to maintain breastfeeding while supplementing with formula, a lactation consultant can help you do this in a way that protects your supply.

Where to get help in Australia

Breastfeeding support is one area where getting help early produces significantly better outcomes than waiting until you're exhausted and overwhelmed.

The Australian Breastfeeding Association helpline is available on 1800 686 268, seven days a week, staffed by trained breastfeeding counsellors. This is the most accessible first point of contact for most women.

Your child and family health nurse provides breastfeeding assessment and support at your early postnatal appointments and between them if needed. Private lactation consultants, who can often do home visits, are particularly useful for complex issues including latch problems, tongue tie, and supply management.

Your GP is the right contact for mastitis, thrush, and any medical concerns. They can also refer you to a specialist lactation consultant if needed.
