The first week of breastfeeding is unlike any other week in your life.
You are recovering from birth, running almost entirely on adrenaline, learning to read a human being you met days ago, and simultaneously trying to establish one of the most complex and demanding physical skills your body will ever perform. All while people ask you constantly whether the baby is sleeping, whether they’re feeding well, and whether you’re enjoying every moment.
No pressure.
The truth is that the first week of breastfeeding is hard for most people — even when it’s going well. It is intense, relentless, sometimes painful, and often nothing like the serene images you may have seen. Knowing what is genuinely normal can make an enormous difference to how you experience those first days and whether you seek help when you actually need it.
This post is your honest guide to what the first week of breastfeeding actually looks like — the normal parts, the parts that feel alarming but aren’t, and the parts that genuinely need attention.
Before the Milk Comes In — Colostrum
In the first few days after birth, your breasts produce colostrum — a thick, golden, highly concentrated fluid that is perfectly designed for your newborn’s immature digestive system. It is produced in small quantities, which can feel worrying when you’re trying to gauge whether your baby is getting enough.
But here is the reassurance: small quantities are exactly right. Your newborn’s stomach is the size of a marble in the first day or two of life. It stretches to roughly the size of a ping pong ball by day three. Colostrum is produced in precisely the volumes your baby needs at each stage — dense, immune-boosting, and perfectly calibrated.
Colostrum is also a natural laxative, helping your baby pass meconium — the thick, dark, tar-like substance that has been in their bowel since before birth. The sooner meconium is cleared, the lower the risk of jaundice. Frequent feeding in those first hours and days is one of the most important things you can do.
What you might notice: You may not be able to express much colostrum by hand — a few drops is completely normal. Your breasts may not feel full or heavy yet. This does not mean there is nothing there.
Day One and Two — Finding Your Feet
In the first 24 hours, most babies are relatively alert and interested in feeding — a window that nature has designed to help get breastfeeding started. Make the most of it. Skin-to-skin contact is one of the most powerful tools available to you in these early hours: it keeps your baby calm, regulates their temperature and blood sugar, and stimulates their feeding instincts.
Feeding frequency: Aim to feed your baby at least 8–12 times in every 24 hours from birth. Yes, that is roughly every two hours around the clock. This frequency is not a sign that something is wrong — it is what stimulates your milk production and establishes the supply-and-demand system that breastfeeding runs on. The more your baby feeds in these early days, the stronger and faster your supply will establish.
Latching: Getting a good latch takes practice — for both of you. In the early days, many parents find latching uncomfortable, unpredictable, or simply baffling. Midwives and maternity support workers on the postnatal ward should be available to help. Ask every time you need support and don’t feel you should be managing alone. If you’re at home, your community midwife is your first port of call.
A good latch should feel like strong suction — not like someone chewing the end of your finger. Sharp, pinching, or biting pain throughout a feed is a sign the latch needs adjusting.
Nappies: On day one, expect at least one wet nappy and one dirty nappy. Stools will be dark green-black meconium at this stage — this is normal and expected.
Day Two to Three — The Transition
This is often the day that catches new parents off guard.
Your baby may become more unsettled and seem to want to feed constantly — sometimes for hours at a stretch. This is completely normal behaviour known as cluster feeding, and it serves an important purpose: it signals to your body to increase milk production in preparation for your milk coming in.
Cluster feeding in the evenings is particularly common and can feel relentless. It does not mean your baby is starving. It does not mean you don’t have enough milk. It means your baby is doing exactly what nature has programmed them to do.
The second night: There is a well-known phenomenon in breastfeeding support called the “second night syndrome.” On the second night after birth, many babies feed almost continuously, sleep very little, and cry a great deal. It is exhausting and alarming in equal measure. If you know it’s coming, it’s significantly less frightening. It passes.
Nappies on day two: At least two wet nappies and continued meconium stools, which may begin to look slightly lighter — moving from black to dark greenish-brown.
Day Three to Five — Milk Coming In
For most people, mature milk comes in somewhere between day two and day five, though the timing varies — it can be later after a caesarean section or a traumatic birth.
When your milk comes in, you will almost certainly know about it. Your breasts will likely become significantly fuller, heavier, and possibly quite firm. Some women experience engorgement — where the breasts become very hard, swollen, and uncomfortable — and the skin may feel tight and shiny. This can make it harder for your baby to latch.
Managing engorgement:
- Feed frequently — the most effective way to manage engorgement is to keep milk moving
- If your baby is struggling to latch onto a very firm breast, hand express a little milk before the feed to soften the areola
- A cool compress or chilled (not frozen) cabbage leaf applied to the breast between feeds can reduce inflammation and provide relief
- Wear a well-fitting, supportive but not constricting bra
- Avoid pumping extensively to relieve engorgement — this signals your body to produce more, which can worsen the problem
Engorgement usually improves within a few days as your supply regulates to your baby’s needs.
Nappies at day three to five: By day four or five you should be seeing at least five to six wet nappies per day and at least two to three yellow, seedy stools. The transition from dark meconium to yellow breastfed stools is a very reassuring sign that your baby is taking in your mature milk.
Day Five to Seven — Settling Into a Pattern
By the end of the first week, many families start to feel the faintest sense of rhythm beginning to emerge. Not a schedule exactly — breastfed babies don’t work on schedules — but a slightly more predictable ebb and flow.
Your milk supply is still establishing itself during this period, and frequent feeding remains very important. This is not the time to try to stretch feeds out or introduce a routine. Following your baby’s cues — feeding whenever they show signs of hunger — is the most effective way to build a strong, robust supply.
Signs feeding is going well at the end of week one:
- Five to six (or more) wet nappies per day
- Regular yellow stools — at least two to three per day, though some breastfed babies will go more frequently than this
- Your baby has returned to, or is close to returning to, birth weight
- Your baby feeds actively, swallows audibly, and comes off the breast looking relaxed and satisfied
- Your nipples are sore at the start of feeds but ease during — and are not cracked, bleeding, or damaged
The Things That Feel Alarming But Usually Aren’t
Your breasts feel completely empty between feeds. As engorgement settles — usually by three to six weeks — many women find their breasts feel soft between feeds rather than full. This is supply regulating to match your baby’s needs. Soft does not mean empty. Milk is being made continuously.
Your baby feeds for a very long time. In the early weeks, feeds of 30–45 minutes are entirely normal. Some babies are efficient feeders and some are slow and leisurely — both are fine, as long as milk transfer is happening.
Your baby cries immediately after a feed. Not all crying after feeding is hunger. Wind, overstimulation, tiredness, or simply wanting closeness are all common reasons babies cry after feeds.
You can’t express much milk. The amount you can express tells you very little about your supply. Your baby is significantly more efficient at the breast than any pump.
Your baby loses weight. Almost all babies lose weight in the first few days after birth. A loss of up to 7% of birth weight is expected and normal. Your midwife will monitor this closely.
Your baby is very yellow. Mild jaundice in the first week is extremely common, caused by the normal breakdown of fetal red blood cells. It usually resolves on its own with frequent feeding. However, significant jaundice — particularly if your baby is very sleepy and difficult to rouse for feeds — should always be assessed by your midwife or GP promptly.
The Things That Do Need Attention
Please do seek support promptly if any of the following apply:
- Nipple pain that is severe, worsening, or causing visible damage — cracking, bleeding, or blistering
- Fewer than five to six wet nappies per day by day four or five
- Stools that haven’t transitioned from meconium to yellow by day five
- Your baby has lost more than 10% of birth weight, or weight loss is continuing beyond day four or five
- Your baby is very difficult to rouse for feeds, or is feeding but not swallowing
- You have a hard, hot, red area on your breast, or fever and flu-like symptoms — this may indicate mastitis and requires medical attention
- You are struggling significantly with your mental health — please tell your midwife or health visitor
None of these necessarily mean that breastfeeding is failing or that you need to stop. Most have addressable causes. But they do need to be looked at promptly, because early support makes a significant difference to outcomes.
A Word About the Emotional Side
Nobody talks enough about how emotionally intense the first week of breastfeeding is.
The hormonal fluctuation in the days after birth is seismic. Many women experience the “baby blues” around day three or four — a sudden surge of tearfulness, overwhelm, and anxiety that coincides, cruelly, with milk coming in and cluster feeding. This is common, hormonally driven, and usually brief.
But the first week of breastfeeding also brings its own emotional weight. The relentlessness of feeding every two hours. The uncertainty about whether it’s working. The vulnerability of asking for help from a stream of strangers. The gap between what you expected and what you’re actually experiencing.
If you are finding the first week harder than you expected — emotionally as well as physically — please tell someone. Your midwife, your health visitor, your partner, a friend. You don’t have to be managing perfectly. You don’t have to be enjoying every moment. You just have to keep going, one feed at a time.
And if feeding is painful, or something doesn’t feel right, please reach out for specialist support sooner rather than later. The first week is the hardest part of the learning curve — and with the right help, it does get better.
