Breastfeeding in the First 6 Weeks

This blog is written by registered midwife Aliza Carr from Bumpnbub

The first six weeks of breastfeeding can feel like a whirlwind—equal parts wonder, exhaustion, and learning on the go. As a midwife (and mum myself), I’ve seen countless women navigate these early weeks, and I promise you’re not alone if it all feels overwhelming. Here’s what you can expect, along with a few tips to help you find your footing.

1. The Early Days: Colostrum and Engorgement

Right after birth, your body produces colostrum, often called “liquid gold” for its rich nutrients and antibodies. Around day 3 or 4, you may notice your breasts becoming firmer and fuller as mature milk comes in—sometimes bringing uncomfortable engorgement. Frequent feeds, warm compresses, and gentle breast massage can help ease any tightness. Whilst you’re in hospital or under the care of a midwife, it can be a great idea to have them assess and assist with each feed in those early days to ensure bub is getting a great latch, and help you with positioning.

2. Finding Your Rhythm and Latch

Your baby will likely feed anywhere from 8–12 times a day (or more!) during these early weeks. Every mother-baby pair is unique, so don’t worry if your feeding sessions feel long or constant at first—your baby is helping build up your milk supply. If you’re experiencing nipple pain or damage, consider reaching out to a midwife or lactation consultant early on. A deep, comfortable latch is the key to reducing soreness and ensuring bub gets plenty of milk.

3. Growth Spurts and Cluster Feeding

Be prepared for days (and nights!) when it feels like your baby wants to feed non-stop. These “cluster feeding” stretches often coincide with growth spurts, helping your milk supply adjust to meet your baby’s increasing appetite. It can be tiring, but staying hydrated, fueling yourself with nutritious snacks, and leaning on your support system can make all the difference.

4. Mood Swings and Emotional Highs (and Lows)

Breastfeeding is an intimate experience that can leave you feeling deeply connected and elated—or teary, sore, and unsure—sometimes within the same day. Hormonal changes are huge in the first six weeks, so seek help if you’re feeling anxious or low. Family, friends, or a healthcare professional can offer the support and reassurance you need.

5. Tracking Wet Nappies and Weight Gain

Research says that one of the biggest concerns mamas have is if their baby is getting enough milk. Whilst we know that only a very small percentage of mums don’t make quite enough milk for their baby, a huge amount of mums share this concern. Keep an eye on wet nappies (they should increase each day until about day 7) and your baby’s weight. Most babies lose some weight in the first few days which is very normal, then gradually gain it back by around two weeks. If you’re ever unsure, never hesitate to pop in for a weight check or call your healthcare provider.

6. Looking After You

Your comfort matters just as much as your baby’s: try different nursing positions (like side-lying if you’re exhausted!) and stay hydrated—keeping a water bottle handy during feeds helps you remember to sip regularly. Rest when you can—those catnaps can recharge your batteries between feeds.

The first six weeks, you and your baby are learning how to breastfeed together—so be patient with yourself. If you need help along the way—reassurance, practical tips, or more specialised support—reach out. Trust your instincts, lean on your village, and remember this journey is ever-evolving. You’ve got this, mama!

Where to find support in Australia

The first six weeks come with a lot of questions, and you are not meant to have all the answers. Australia has excellent, free support, so lean on it early and often:

• Australian Breastfeeding Association National Breastfeeding Helpline, 1800 686 268. Trained counsellors are available any time, day or night.
• Your child health nurse and midwife. They can check your baby's weight and feeding, and they have seen it all before.
• The Raising Children Network, Australia's trusted parenting site, for clear guides on newborn feeding and sleep.
• Pregnancy, Birth and Baby, a national service with a free helpline on 1800 882 436.

If feeding hurts, your baby is not settling, or you simply feel uneasy, reach out. Asking for help early is one of the kindest things you can do for both of you.

A note on those first days in hospital and home

In the early days your milk moves from colostrum, the rich first milk, to mature milk, and your breasts may feel full or engorged as it comes in. Skin-to-skin contact, frequent feeds, and a good latch all help your supply settle. Australian hospitals and midwives encourage rooming in and feeding on demand, so follow your baby's cues rather than the clock. If you are collecting those precious early drops, a colostrum collector makes it easier, and our breast care range can help with engorgement and sore nipples along the way.

It gets easier

Six weeks is a real milestone. Cluster feeding eases, your supply finds its rhythm, and that first proper smile makes the hard nights feel worth it. Be gentle with yourself, take the help on offer, and trust that you and your baby are learning this together.
