Newborn Care: A Complete Guide for the First Weeks

The first weeks with a newborn are unlike anything else. Nothing fully prepares you for the combination of exhaustion, love, uncertainty, and sheer volume of questions that arrive alongside a new baby. This guide covers the practical realities of newborn care: what happens in the first 24 hours, how to feed, how to help your baby sleep safely, and which warning signs always warrant a call to the midwife.

Newborns change rapidly in the first weeks. Understanding the normal patterns — including what looks alarming but is not — helps you respond calmly and identify the things that genuinely require attention.

⚠️ MEDICAL DISCLAIMER

This article is educational information only. It is NOT a substitute for professional medical advice, diagnosis, or treatment.

Always consult your pediatrician or healthcare provider before making any medical decisions for your baby or child. Every baby is unique, and professional medical guidance is essential.

In case of emergency, call 911 or your local emergency number.

The First 24 Hours

The hours immediately after birth involve a series of checks and decisions that can feel overwhelming when you are also trying to process the birth itself.

Skin-to-Skin Contact

Immediate skin-to-skin contact — placing the newborn directly on the mother's (or partner's) bare chest — is recommended by the World Health Organization (WHO) and the NHS for all newborns who are breathing and stable. It helps regulate the baby's temperature, heart rate, and blood sugar, and stimulates the release of oxytocin in both mother and baby. It also supports the initiation of breastfeeding by triggering the rooting reflex.

The APGAR Score

At one minute and five minutes after birth, midwives or doctors assess the baby using the APGAR score — a rapid evaluation of Appearance (skin colour), Pulse, Grimace (reflex), Activity (muscle tone), and Respiration. Each category is scored 0–2. A score of 7 or above is normal. Lower scores prompt additional support or monitoring.

The Vitamin K Injection

Newborns are born with low levels of vitamin K, which is needed for blood clotting. Without supplementation, a small number of babies develop vitamin K deficiency bleeding (VKDB), which can be life-threatening. The NHS offers an intramuscular vitamin K injection at birth, which provides the most reliable protection. An oral vitamin K programme is available as an alternative but requires multiple doses. The injection is recommended by the NHS and AAP.

Feeding Your Newborn

Breastfeeding

The WHO recommends exclusive breastfeeding for the first six months of life. In the UK, the NHS supports this recommendation while recognising that every family's situation is different.

Breastfeeding works best when initiated early (ideally within the first hour), with the baby feeding on demand — typically 8–12 times in 24 hours in the early weeks. The first milk, colostrum, is produced in small quantities but is highly concentrated with antibodies and nutrients perfectly matched to a newborn's needs.

Key breastfeeding principles:

• Positioning and attachment: A deep latch, where the baby takes a large mouthful of breast tissue (not just the nipple), prevents soreness and ensures effective milk transfer
• Feeding cues: Look for rooting (turning the head and opening the mouth), sucking on hands, or restlessness. Crying is a late feeding cue
• Supply and demand: The more frequently and effectively the baby feeds, the more milk is produced. Introducing formula in the early weeks can interfere with establishing supply

If breastfeeding is painful beyond the first few seconds of a feed, or if you have concerns about supply or the baby's weight gain, ask for a referral to an infant feeding specialist or lactation consultant.

Formula Feeding

For those not breastfeeding or supplementing with formula, safe preparation is essential. NHS guidance on making up formula feeds:

• Always use freshly boiled water that has been allowed to cool for no more than 30 minutes (water should be at least 70°C to kill any bacteria in the powder)
• Use the scoop provided and level it off — do not pack or heap
• Make feeds fresh each time rather than in advance where possible
• Sterilise all equipment (bottles, teats, caps) before each use — an electric steam steriliser is the most efficient method

Feeding Cues vs. Schedules

Newborns do not arrive with a schedule. Feeding on demand — responding to hunger cues rather than the clock — is physiologically appropriate in the first weeks. By around 6–8 weeks, many babies begin to show patterns, though not all do. Trying to impose a rigid schedule in the first four weeks frequently results in supply issues with breastfeeding and unnecessary distress.

Safe Sleep

Safe sleep practice is one of the most important things you can do to reduce the risk of sudden infant death syndrome (SIDS). The Lullaby Trust, which leads SIDS awareness in the UK, sets out clear guidance based on the research evidence.

The Safe Sleep Guidelines

• Back to sleep: Always place a baby on their back to sleep — never on their front or side
• Firm, flat, separate surface: A firm, flat mattress in a cot or Moses basket is recommended. The surface should not allow the baby to sink in
• Room-share for at least 6 months: Babies should sleep in the same room as a parent or carer for every sleep — day and night — for at least the first six months. This significantly reduces SIDS risk
• No loose bedding, bumpers, or soft toys: These all pose suffocation and overheating risks. A well-fitted cellular blanket tucked no higher than the shoulders, or a baby sleeping bag in the correct tog for the temperature, are the safe options
• No smoking: Exposure to cigarette smoke during pregnancy and after birth significantly increases SIDS risk
• Temperature: Keep the room at 16–20°C. Overheating is a risk factor

The guidance on bed-sharing is nuanced — the safest place for a baby to sleep is always a firm, flat, separate surface. If a parent falls asleep while feeding, having a safe surface prepared in advance (rather than a sofa or armchair, which carry the highest risk) reduces harm.

Umbilical Cord Care

The umbilical cord stump dries and falls off within 7–21 days. NHS guidance recommends keeping it dry and clean:

• Fold down the nappy front to keep it exposed to air
• Clean around it with a cotton wool pad dipped in clean water if needed, then dry gently
• Avoid submerging in a bath until it has fallen off and the area has fully healed

Signs of infection to report to your midwife include redness or swelling of the surrounding skin, a discharge that smells unpleasant, or if the baby appears unwell.

Bathing a Newborn

Newborns do not need daily baths. The NHS recommends 2–3 times per week as sufficient for the first few months. In between baths, "top and tailing" — cleaning the face, neck, hands, and nappy area with cotton wool and warm water — keeps the baby clean.

For the first bath after the cord has fallen off:

• Use a purpose-made baby bath or a clean washing-up bowl
• Water temperature should be 37–38°C — check with your elbow, which is more sensitive than your wrist
• Lower the baby in gently, feet first, supporting the head at all times
• Use plain water only or a very small amount of mild, fragrance-free baby wash
• Never leave a baby unattended in water, even for a moment

Nappy Care

A newborn's first stools are meconium — dark green-black and sticky. Over the first 2–4 days, as milk feeding is established, stools transition to a greenish-yellow, then to mustard-yellow (for breastfed babies) or pale yellow-tan (for formula-fed babies). This transition is a reassuring sign that feeding is going well.

Normal stool frequency varies enormously — breastfed babies may have a dirty nappy after every feed, or go several days without one. Both are normal. Formula-fed babies tend to have more predictable bowel movements.

To prevent nappy rash, change nappies frequently, clean thoroughly at each change, and apply a thin layer of barrier cream (such as zinc-based cream) as a protective layer at each change.

Jaundice in Newborns

Neonatal jaundice — yellowing of the skin and whites of the eyes — affects approximately 60% of newborns and up to 80% of premature babies, according to NICE. It is caused by a build-up of bilirubin as the baby's immature liver works to break down the extra red blood cells present at birth.

Physiological jaundice appears on days 2–3, peaks around days 4–5, and usually resolves within 2 weeks. It requires monitoring but not treatment in mild cases. Frequent feeding helps the liver clear bilirubin.

Pathological jaundice appears within the first 24 hours, rises rapidly, or persists beyond 14 days (21 days in premature babies). This requires investigation and possibly treatment.

Phototherapy — placing the baby under a special light — is the most common treatment and is very effective. The light helps break down bilirubin in the skin.

Any yellow skin persisting beyond day 14 in a full-term baby, or any jaundice appearing in the first 24 hours, should be reported to the midwife or neonatal team promptly.

Newborn Checks and Screening Tests

Newborn Physical Examination

A full physical examination is offered within 72 hours of birth and again at 6–8 weeks by a GP or paediatrician. It checks the eyes, heart, hips, and (in boys) the testes.

The Newborn Blood Spot Test (Heel Prick)

Offered at around 5 days old, this test screens for 9 conditions including phenylketonuria (PKU), congenital hypothyroidism, cystic fibrosis, and sickle cell disease. Early identification allows treatment to begin before symptoms develop.

Newborn Hearing Screening

Offered before discharge from the maternity unit or shortly after, this automated test takes a few minutes and identifies permanent hearing loss early, when support is most effective.

Warning Signs to Report to Your Midwife

Contact your midwife or maternity unit promptly if your newborn:

• Has a temperature above 38°C in the first 3 months (any fever in a very young baby is a medical emergency)
• Is having difficulty feeding or refusing feeds for more than one feed
• Has not regained their birth weight by 2 weeks
• Has fewer than 6 wet nappies in 24 hours after day 4
• Shows signs of breathing difficulty: rapid breathing, grunting, blue lips or skin
• Has persistent yellow skin or eyes after day 14
• Is unusually drowsy or difficult to rouse
• Has a bulging fontanelle (the soft spot on the head)

Trust your instincts. If something seems wrong, seek help — do not wait for the next scheduled appointment.

Frequently Asked Questions

How do I know if my baby is getting enough milk when breastfeeding?

The most reliable signs are: at least 6 wet nappies per day from day 5, yellow stools after day 4, the baby appears satisfied after feeds, and weight gain is on track (most babies lose up to 7–10% of birth weight in the first few days, then regain it by around 2 weeks).

Is it normal for a newborn to sleep so much?

Yes. Newborns sleep 16–18 hours per day in the early weeks, waking primarily to feed. If a baby is sleeping through feeds or is very difficult to rouse, contact your midwife — very sleepy feeding behaviour can indicate jaundice or low blood sugar.

When does the umbilical cord fall off?

Usually between 7 and 21 days. Keep it dry and clean, and let it fall off naturally. Do not pull it even if it looks loose.

Should I wake a sleeping newborn to feed?

In the first 2 weeks, if your baby has not fed for 4 hours during the day (3 hours at night), wake them to feed. This is important for establishing supply and ensuring adequate weight gain. After the 2-week check, if weight gain is on track, you can begin to follow the baby's cues more.

What temperature should a newborn's room be?

The Lullaby Trust recommends 16–20°C. Use a room thermometer to monitor this. A baby who is too hot will feel sweaty, have flushed cheeks, or be restless.

My baby has a rash — should I be worried?

Many newborn rashes are completely normal. Erythema toxicum (red blotchy patches), milia (small white spots on the nose), and baby acne are all benign and resolve on their own. Any rash combined with fever, a rash that looks like small purple or red spots that do not fade when pressed (a glass test), or a rash that seems to concern the baby should be assessed by a doctor immediately.

Key Takeaways

• Immediate skin-to-skin contact after birth supports temperature regulation, breastfeeding initiation, and bonding, and is recommended by the WHO for all stable newborns.
• Safe sleep means always on the back, on a firm flat surface, in the same room as a parent for at least the first 6 months, with no loose bedding or soft objects.
• Neonatal jaundice is very common and usually resolves on its own, but jaundice within the first 24 hours or persisting after day 14 always needs medical review.
• Feeding on demand — responding to hunger cues rather than the clock — is the appropriate approach in the first weeks for both breastfed and formula-fed babies.
• The newborn blood spot test, hearing screening, and physical examination are all offered as standard NHS checks and should not be missed, as early detection significantly improves outcomes.
• Fever above 38°C in any baby under 3 months requires same-day medical assessment — it is never safe to manage this at home with paracetamol alone at this age.
