Premature Babies: What to Expect & Support Guide for Parents

If your baby has arrived early, it’s completely natural to feel a mix of emotions. You may feel worried, frightened or unsure about what lies ahead, while you also may be feeling relief that your baby is here and receiving the care they need.

Around 1 in 10 babies worldwide are born prematurely (WHO 2023), so although this experience can feel isolating, you are not alone. For many parents, this is an unexpected introduction to a new world of medical language and specialist equipment that you may have never heard of before.

Your neonatal team is there to guide you, answer questions, and support both you and your baby every step of the way.

This guide is also here to help you feel more informed and supported. It includes;

• What it means for a baby to be born premature
• Why premature birth can happen
• What to expect in the early days (including the NICU)
• How to support your baby’s growth and development

A premature (or preterm) baby is born before 37 weeks (NHS 2024) of pregnancy. It is important to remember that every baby is unique. Some babies need only a little extra monitoring at first, while others need more specialised support while their lungs, feeding skills, and overall body control start to become more mature.

Healthcare teams often describe prematurity in week ranges.

• Moderate to late preterm (32 to 37 weeks): This is the largest majority of preterm births. Babies in this age range may need help with breathing, feeding, and staying warm, especially if born earlier (around 32 weeks). Their hospital stay can vary depending on their individual needs and how quickly they build strength and coordination.
• Very preterm (28 to 32 weeks): Babies usually need more intensive medical care and spend longer in the neonatal unit. They often require support with breathing and feeding. For example, a baby born at 30 weeks will typically need time to grow and develop in specialist care before going home.
• Extremely preterm (before 28 weeks): These babies usually need highly specialised care in a Neonatal Intensive Care Unit (NICU). As they are born very early, they often need extra support and a longer stay in hospital while they grow and develop. (NICE 2022)

• About 1 in 10 babies are born prematurely worldwide (WHO 2023)
• In the UK, around 60,000 babies are born prematurely each year. (Kayode et al 2024)
• Most premature births (around three-quarters) are late preterm (34–36 weeks). (BAPM 2023)
• Medical advances mean survival rates and long-term outcomes have improved greatly over recent decades. (ESPGHAN 2022)

This is one of the most common questions parents ask when they know their baby may be arriving early. The most honest answer is that every week (and even every day) in the womb matters for a baby’s development.

In general, babies born at around 24 weeks or later can survive with specialist neonatal care, and outcomes usually improve with each additional week. Babies born at around 32 weeks and beyond often have excellent outcomes with appropriate medical support. By 34 to 36 weeks, most babies face fewer complications and have shorter hospital stays, though they may still need extra help with feeding, temperature, or jaundice.

Sometimes there is no clear reason why a baby is born early. For many families, a premature birth comes as a complete surprise, bringing with it lots of questions and emotions. It is important to remember that, in many cases, preterm birth is not caused by anything a parent did or did not do.

While there are some known causes and risk factors, many families never receive a clear explanation for why their baby arrived early.

Doctors generally describe premature birth in two ways. Sometimes labour starts on its own before 37 weeks of pregnancy, known as a spontaneous preterm birth. In other situations, the medical team may recommend an early delivery because it is the safest option for either mum, baby or both. This is known as a medically indicated preterm birth.

Spontaneous preterm birth (labour starts on its own):

• Waters breaking early (premature rupture of membranes)
• Labour starting early without warning
• Infections (such as in the womb or urinary tract)
• Cervix opening too early (cervical insufficiency)
• Multiple pregnancy (twins, triplets, or more)

Medically indicated preterm birth (early delivery is recommended):

• Pre-eclampsia (high blood pressure in pregnancy)
• Placental problems (for example, not working well or in the wrong position)
• Baby not growing well in the womb
• Bleeding during pregnancy
• Maternal health conditions (such as diabetes or kidney disease)

(NICE 2022) (WHO 2023) (House of Lords 2024)

Some factors may increase the likelihood of preterm birth, but some premature births happen without any clear cause.

Previous pregnancy history:

• Having had a premature baby before (often the strongest predictor)
• Previous late miscarriage

Current pregnancy factors:

• Carrying twins, triplets, or more
• Very short time between pregnancies (less than 6 months)
• Pregnancy through IVF or fertility treatment
• Problems with the placenta, womb, or cervix
• Too much or too little amniotic fluid
• Bleeding in pregnancy

General health and lifestyle factors^1,2:

• Age (under 18 or over 35)
• Being significantly underweight or overweight
• Chronic health conditions (diabetes, high blood pressure, kidney disease)
• Infections during pregnancy
• Previous surgery on the cervix or womb
• Smoking during pregnancy
• Alcohol or drug use
• High stress levels
• Lack of prenatal care

(NICE 2022, Kayode et al 2024) 

Meeting your premature baby for the first time can feel emotional and sometimes unexpected. Your baby may look smaller or more delicate than you imagined, as they are continuing to grow and develop outside the womb.

• Size and weight: Premature babies are often much smaller than full-term newborns. Some fit in the palm of your hand at first, especially if they’re born very early.
• Skin: Skin may be thin and fragile, sometimes looking reddish or translucent with visible veins. As your baby matures and gains fat, their skin usually becomes thicker and less see-through.
• Hair and body: Many preterm babies have soft, fine hair called lanugo on their body or face. This often reduces over time.
• Facial features and body shape: Their head may look larger compared to their body, and their limbs may appear slender because they have less body fat.
• Movement: Premature babies can be sleepier, less active, have weaker reflexes and tire quickly.

It’s always okay to ask the neonatal team for advice and what’s normal for your baby’s age and development.

The neonatal unit can feel overwhelming at times. There may be many wires, beeping alarms, bright lights, and lot of medical staff. Although it may feel unfamiliar at first, many parents say the hospital gradually becomes a place of reassurance, knowing that every piece of equipment and every member of the team is there to monitor, protect and care for their baby.

In hospital your baby may be in an incubator (a clear, heated cot) or under a radiant warmer. Monitors track vital signs like heart rate, breathing, oxygen levels, and temperature. You’ll see staff washing hands frequently and following strict infection control steps because preterm babies’ immune systems are still developing (van den Akker et al 2020)

The alarms may make you wonder what is happening, but they are often triggered by small changes (or a sensor that has moved). They don’t always mean something is wrong, and the team responds quickly when something needs checking.

Support depends on how early your baby was born and how they’re doing day to day. Common supports include:

• Breathing support: Many premature babies need help breathing because their lungs are still developing. This may include oxygen support, CPAP (Continuous Positive Airway Pressure), or a ventilator. Some babies receive surfactant, a treatment that helps the lungs work more effectively.
• Feeding support : Premature babies often can’t coordinate sucking, swallowing, and breathing yet (this usually develops around 34 weeks) Bliss 2024. Milk may be given through a feeding tube, and some babies need nutrients through a vein at first (parenteral nutrition). Breast milk is especially beneficial; many mums express milk to be given until direct feeding from the breast is possible (Delsoglio et al 2024).
• Temperature regulation: Premature babies often can’t regulate their temperature well. Incubators keep the air warm and sometimes humid. Skin-to-skin contact (kangaroo care) also helps regulate temperature and supports bonding with your baby.
• Monitoring: Sticky pads, small wires, and sensors continuously monitor heart rate, breathing rate, and oxygen levels, helping staff respond quickly if your baby needs support.
• Other common care: Treatment for jaundice, support with blood sugar levels, help managing apnoea (pauses in breathing), and careful infection screening if there are concerns.

Although your baby is receiving specialist care, you are the most important people in their world. Your touch, voice and presence provide comfort and reassurance, and your neonatal team will encourage you to be involved in your baby's care whenever it's safe to do so. This can be nappy changes, supporting feeding and bathing.

Kangaroo care (skin-to-skin) One of the most special ways you can care for your baby is through skin-to-skin contact, often called kangaroo care. This can help to:

• Stabilise heart rate and breathing
• Improved oxygen levels
• Improve temperature regulation
• Support milk supply and breastfeeding
• With comfort and bonding for both baby and parent

It is important that you also take care of yourself; ask questions, take breaks, eat, and rest when you can.

Every baby's journey neonatal care is different, and it's okay if it takes time to feel settled. As you get to know your baby and the team caring for them, you'll grow in confidence. Remember, you're an important part of your baby's care, and your neonatal team is there to support you both throughout your journey.

Premature babies often follow their own timeline, and progress is tracked by using corrected age (also called adjusted age). Corrected age is based on your baby’s due date, not their birthday.

How it works: take your baby’s actual age and subtract how many weeks early they were born (from 40 weeks). For example, if your baby is 12 weeks old but was born 8 weeks early, their corrected age is 4 weeks.

Corrected age helps you compare milestones in your babies development and is usually used until around 2 years old.

Some premature babies need extra support with movement, feeding, learning, hearing, vision, or breathing. Regular follow-up appointments are there to track development and offer help early when needed.

It’s common for parents to feel scared, overwhelmed or worried about their baby. Some parents feel an instant connection, while others may feel detached at first, especially when their baby is in an incubator or they may not be able to hold them right away. All of these responses can be normal, and feelings can change from hour to hour.

Support can come from many places:

• Talk to the NICU team: ask questions, request updates, and tell them what you’re finding hard. They can explain what’s happening in plain language.
• Connect with other parents: many hospitals and charities offer peer support that helps you feel less alone.
• Charities and organisations: in the UK, Bliss offers information and support for families of premature and sick babies. The NHS also provides guidance and can signpost local services.
• Mental health support: if anxiety, low mood, intrusive thoughts, or trauma symptoms are becoming overwhelming, speak to your GP, health visitor, or the hospital team.

Be kind to yourself. Try to rest when you can, eat regularly, and don’t hesitate to ask for support.

Preterm birth can't always be prevented, and many babies are born early without a clear reason. Attending your antenatal appointments, treating infections promptly and following your healthcare team's advice may reduce the risk in some pregnancies. If you've previously had a preterm birth, your team may offer extra monitoring and support. If you're worried about symptoms such as pain, bleeding, fluid loss or regular tightenings, contact your maternity unit straight away.

Many babies born prematurely catch up over time, especially when milestones are measured using corrected age (link to article). Every baby develops at their own pace, and your follow-up team will monitor your baby's progress and offer extra support if needed.

Many babies born prematurely grow up to live healthy lives. Every baby's journey is different, but advances in neonatal care have greatly improved outcomes. Your healthcare team will continue to monitor your baby's progress and support you every step of the way.

Breastfeeding is recommended as the best feed for premature babies. Some premature babies can’t feed at the breast straight away, but you can usually express milk and it can be given via a feeding tube until your baby is ready to take milk orally. Many babies move to breastfeeding as their strength and coordination improves. Neonatal nurses, lactation consultants and infant feeding specialists can help you with expressing, supply, and positioning when your baby is ready.

The time can vary and can depend on their development. Some babies go home around their due date, but many go home earlier or later depending on their needs.

Many premature babies often sleep a lot because growing takes a lot of energy. They can also tire quickly during feeds especially early on. Sleep patterns may change as your baby gets near their due date. If you’re worried your baby is too sleepy to feed, or hard to wake, ask for support.

If you notice your baby isn’t meeting milestones for their corrected age, has ongoing feeding difficulties, or you’re worried about their, movement, vision, hearing, or responsiveness, talk to a healthcare professional. Trust your instincts, parents often spot small changes first.
