The first week is often the hardest — milk that seems too little, sore breasts, a crying baby, and the constant question: "Is this working?" This guide covers what's physiologically expected day by day, how to recognize that things are on track, and when to seek help — based on recommendations from the **American Academy of Pediatrics (AAP)**, the **World Health Organization (WHO)** and the **Academy of Breastfeeding Medicine (ABM)**. ## The first week, day by day There's no exact timeline — every mother-baby pair finds the rhythm in their own time — but there are common patterns that help you tell whether things are progressing: | Day | What to expect | |---|---| | **Day 1** | Small amounts of colostrum (5–15 ml per feed). Baby alert in the first 2 hours, then often sleeps a lot. | | **Day 2** | Cluster feeding: baby wakes more often and wants to nurse frequently. This boosts production. | | **Day 3–5** | "Milk coming in" (lactogenesis II): breasts feel fuller and warmer. Volume per feed grows to 30–60 ml. | | **Day 5–7** | Feeds spread out (about 8–12 per day). Wet, yellow diapers confirm adequate intake. | | **Day 10–14** | Baby should be back to birth weight. Production starts adjusting to demand. | ## Colostrum: small in volume, huge in value In the first days, the milk is yellowish, thick, and small in quantity — that's **colostrum**. It seems like very little, but it's exactly what the newborn needs: a baby's stomach on day 1 is roughly the size of a cherry (5–7 ml), on day 3 it's a walnut (22–27 ml), and by week 1 it's the size of an apricot (45–60 ml). Colostrum is rich in: - **Antibodies (secretory IgA)** that coat the baby's intestine and protect against infection - **Growth factors** that help the digestive tract mature - **High protein concentration** and low fat/lactose — perfect for an immature digestion That's why, even if you give birth and feel "I don't have milk", you almost always do — it's just in a different volume and form than you might expect to see later. ## Milk coming in (lactogenesis II) Between **day 3 and day 5**, the breasts become visibly fuller, heavier, sometimes warm or sore. That's lactogenesis II — the transition from colostrum to transitional milk (and then to mature milk by week 2). Common signs: - Increased breast volume and firmness - Leaking between feeds - Possible temperature spike (don't confuse with fever — without other symptoms) - Baby starts swallowing audibly during the feed If milk coming in is delayed beyond 5 days (which can happen after a c-section, first pregnancy, or mother-baby separation), get guidance. Frequent emptying — by nursing the baby or by hand-expressing — is the main stimulus. ## A good latch: what to watch Most pain during breastfeeding comes from a **poor latch** — not from breastfeeding itself. Signs of a good latch: - The baby's chin **touches the breast** - The mouth is **wide open**, lips flanged outward ("fish mouth") - The **areola shows more above** than below the baby's mouth - You **don't hear clicking** during sucking (clicking usually means broken suction) - Nursing is **comfortable** after the first few seconds - The baby **swallows audibly and rhythmically** once the milk lets down If any of those is missing, it's worth breaking the latch (slip a clean pinky finger into the corner of the mouth to break the suction) and offering again, calmly. Don't push through a bad latch — a crack in the first week sets the whole process back significantly. ## Frequency: on demand, no schedule Newborns nurse **8 to 12 times in 24 hours** on average, but this can vary a lot from one day to the next. There's no minimum interval between feeds, and trying to impose a schedule (every 3 hours, for example) tends to lower supply and frustrate the baby. Normal patterns that often alarm parents: - **Cluster feeding**: stretches (often late afternoon/evening) where the baby wants to nurse every 30–60 minutes for several hours. It's physiological — building supply and organizing sleep. - **Short feeds alternating with long ones**: 5 minutes one hour, 40 minutes the next. That's fine, as long as the baby is active during. - **Waking at night**: in the first months, expecting the baby to "sleep through the night" isn't realistic — and night wakings to nurse are protective against SIDS. The practical rule is: offer the breast whenever you see **early hunger cues** (head turning, opening and closing the mouth, hand to mouth, soft sounds). Waiting for crying makes latching harder. ## How to know your baby is getting enough The best objective indicators aren't "how much" comes out of the breast (which nobody can measure well), but rather: ### Diapers (from day 5 on) - **6 to 8 wet diapers** per 24 hours (clear urine, no strong smell) - **3 to 4 yellow stools** per 24 hours (mustard color, seedy texture) Before day 5, expect one wet diaper per day of life (1 on day 1, 2 on day 2, etc.) and the transition from **meconium** (black, tarry) to yellow stool by day 5. ### Weight - Weight loss up to **7% in the first 3–4 days** is normal - Loss **above 10%** requires immediate evaluation - Birth weight regained by **10–14 days** - After that, average gain of **20–30 g/day** in the first trimester ### Behavior - Baby is **active** during the feed (rhythmic suckling, audible swallowing) - **Comes off the breast spontaneously** when satisfied - Stays **calm between feeds** (not crying constantly) ## Common problems in the first days ### Cracked nipples The cause is almost always a poor latch. Solutions: - **Fix the latch** (on your own or with a lactation consultant) — without that, no cream works - Apply a drop of **your own milk** to the nipple after feeds and let it air-dry - Avoid soap on the area (regular shower water/gel is enough) - **Keep nursing** — stopping usually makes it worse, because milk builds up and causes engorgement Pure lanolin can help as a barrier, but doesn't replace fixing the cause. ### Engorgement Very full, hard, painful breasts — usually between days 3 and 7. The risk is milk stagnating and progressing to mastitis. What to do: - **Empty often**: nursing the baby or hand-expressing/pumping - **Cold compresses** between feeds, **warm** just before (helps the milk flow) - Gentle massage from the chest toward the nipple - If you develop fever above 38 °C (100.4 °F), redness, or intense pain that doesn't go away: it may be mastitis — seek care ### Nipple confusion Early use of a **bottle or pacifier** (before 4 weeks, before breastfeeding is well established) can lead the baby to refuse the breast or "forget" the correct latch. If you really need to supplement, prefer a **cup, dosing spoon, or supplemental nursing system** under guidance. And if formula is the top-up, the [amount-by-age chart](/en/blog/how-much-formula-by-age/) helps you know how much to offer. ### Low supply (real or perceived) Most mothers who feel they have low supply actually have adequate production — but the perception is misleading because breasts feel "empty" after lactogenesis II and the baby starts feeding more efficiently. How to tell the difference: - Baby on track for diapers and weight → supply is fine - Baby with few diapers, losing weight, or chronically irritable even after feeds → get evaluated ## When to get specialized help > **Get a lactation consultant, milk bank, or pediatrician urgently if:** > > - **Persistent pain** that doesn't improve with latch correction > - **Bleeding cracks** or signs of infection (redness, heat, pus) > - **Fever above 38 °C / 100.4 °F** with sore or red breast (suspected mastitis) > - **Baby has lost more than 10%** of birth weight > - **Baby hasn't regained** birth weight by 14 days > - **Fewer than 6 wet diapers** per day after day 5 > - Baby is **lethargic**, hard to wake for feeds, or feeds with great difficulty In most countries, **IBCLC** (International Board Certified Lactation Consultant) directories help locate qualified support: [ilca.org/why-ibclc/falc](https://www.ilca.org/why-ibclc/falc). Many maternity hospitals also offer follow-up with a consultant in the first days after discharge — worth asking. ## Caring for the person breastfeeding Breastfeeding is a full-time job in the first weeks, and everything that supports the parent supports breastfeeding too: - **Hydration**: keep a water bottle nearby. Thirst noticeably increases in the first days. - **Nutrition**: varied, regular meals. There are no universally "forbidden" foods for a breastfeeding parent — restrictions only with clinical indication. - **Sleep in cycles**: sleep when the baby sleeps, even in 1–2 hour stretches - **Support network**: someone to cook, do laundry, hold the baby between feeds. Not a luxury — it protects breastfeeding - **Mental health**: mild sadness in the first 10 days is common (baby blues). Deep sadness, constant crying, anxiety, or disconnection from the baby after week 2 can be postpartum depression — seek professional help, it's treatable and recovery is fast ## When it eases The first week is often the hardest of all of breastfeeding. By **2 to 3 weeks**, in most cases: - The latch is established - Supply has adjusted to the baby's demand - Pain (if any) eases - The schedule becomes more predictable The WHO recommends **exclusive breastfeeding until 6 months** and continued breastfeeding (with complementary foods) **up to 2 years or beyond**. But every breastfeeding decision belongs to the family, and every drop of breast milk counts — there's no "all or nothing". If you're in the first days and it's hard: it really is hard. Get help early, offer the breast often, rest when you can, and remember: in most cases, it gets much better, fast. ## FAQ ### My milk hasn't come in yet — is my baby hungry? Almost never. For the first 2–4 days, what comes out is colostrum — in small volumes (5–15 ml per feed on day 1), because a newborn's stomach is the size of a cherry. That volume is exactly what they need. The 'milk coming in' (lactogenesis II) usually happens between days 3 and 5, with volume increasing alongside. ### How often should the baby breastfeed in the first days? On demand — typically 8 to 12 times in 24 hours, sometimes more. Newborns don't follow a schedule and may cluster feed every hour for stretches and sleep 3 hours at others. There's no minimum interval between feeds. ### How do I know my baby is getting enough? Diapers and weight are the best indicators. From day 5 on, expect 6–8 wet diapers and at least 3–4 yellow stools per day. The baby should be back to birth weight by 10–14 days. An active baby at the breast who comes off on their own and stays calm between feeds is another good sign. ### Is pain during nursing normal? Mild discomfort in the first few seconds can happen at the start, but pain that lasts the entire feed is not normal — it usually points to a poor latch. Get help from a lactation consultant or a milk bank. Cracks, bleeding, or throbbing pain between feeds need evaluation. ### Can I offer formula 'just to top up' in the first days? Only with medical indication. Early formula supplementation without clinical need reduces the milk-production stimulus (which is demand-driven) and can compromise long-term breastfeeding. If you have real concerns about intake, talk to your pediatrician before supplementing on your own. ### When should I see a lactation consultant? Whenever you have persistent pain, latch difficulties, suspected low supply, weight loss greater than 10% in the first days, or simply if something doesn't feel right. The earlier the help, the faster the resolution. In many countries, milk banks and IBCLC consultants offer support in the first weeks postpartum.
