The Neonatal Unit Explained

The three levels, and why your baby is in this one

A neonatal unit is a part of a hospital that cares for babies born early, born with a condition that needs treatment or a low birthweight, or who become ill after birth. In the UK they come in three levels, and the level describes what the unit is staffed and equipped to do — not how worried anyone is.

Special care, level 1 (SCBU or SCU)

For babies who do not need intensive care, most often born after about 32 weeks. Typical care includes tube feeding, monitoring, intravenous antibiotics, phototherapy for jaundice, and stabilising an unwell baby before a transfer.

Local neonatal unit, level 2 (LNU)

For babies needing a higher level of support. The London Neonatal Network describes it as for babies born after 27 weeks and weighing over 1,000g, and it can provide short-term intensive care, usually up to around 48 hours. Bliss describes level 2 as often for babies born between 27 and 32 weeks.

Neonatal intensive care, level 3 (NICU)

The highest level of support, for babies usually born before 27 to 28 weeks and for any baby who needs sustained intensive care. A NICU does everything an LNU and SCBU does, plus long-term ventilation and, in some units, surgery, cardiology or other specialist services.

Two things follow from this. First, a baby who improves may move down a level, or move hospital to be nearer home; a baby who deteriorates may move up. Second, if you are told before birth that your baby will need a NICU, you may be transferred while still pregnant. That is called an in-utero transfer, and it is done because it is safer to move a baby before birth than after.

Transitional care, the fourth thing nobody explains

Alongside the three levels there is transitional care, where your baby stays with you — on the postnatal ward or in a room on the unit — while still getting some support such as tube feeds or temperature monitoring. Some babies born between 34 and 37 weeks are cared for this way, depending on their weight and whether they need any breathing support. If you are offered it, take the offer seriously: it is the step that gets you doing the care with a nurse in the room.

The equipment, in plain words

The machines are the most frightening part of the first hour and the least frightening part of the first week. In broad terms you will see an incubator or heated cot keeping your baby warm; a monitor showing heart rate, breathing rate and oxygen saturation, with a probe taped to a hand or foot; some form of breathing support, which may be a ventilator tube, CPAP prongs in the nose or high-flow oxygen; lines for fluids or nutrition, which may be a drip in a hand or a longer line threaded to a larger vein; and a feeding tube through the nose or mouth.

The alarms are set deliberately sensitive. They go off for probes that have slipped, for a baby who has wriggled, and for real events. Staff read the trend on the screen and the baby in the cot, not the noise. You will learn to do the same, and that shift takes about a week.

Who everybody is

Bedside care is nursing care: a neonatal nurse or nursery nurse who will know your baby better than anyone. Above that sit registrars and consultant neonatologists, with ward rounds usually once or twice a day. Around them are neonatal dietitians, physiotherapists, speech and language therapists working on feeding, pharmacists, infant feeding specialists and often a psychologist or family support worker. Ask who your baby's named nurse is on each shift. It gives you one person to ask everything.

You are not a visitor

Bliss states it plainly: "Parents are not considered visitors. You should be able to be with your baby 24 hours a day." Visiting restrictions apply to other family members, not to you. Everyone entering washes hands and forearms, and units often have a bare-below-the-elbow policy. Family should stay away if they have a cold, flu, COVID, a tummy bug, whooping cough, measles or chickenpox — that is not overcaution, it is the difference between a stable week and a sepsis screen.

You can also do more than sit. Nappy changes, mouth care with your own expressed milk, taking temperatures, tube feeds and skin-to-skin are all things parents are taught to do, and units actively want you doing them.

Ward rounds, and how to get a straight answer

Ward rounds happen once or twice a day and are where your baby's plan is set. You are entitled to be there and units increasingly expect you to be, but the round is fast, technical and not aimed at you. Two habits help. Write your questions down before it starts, because you will forget them. And if the round moves on before you have understood something, say so at the time — the alternative is spending the afternoon reconstructing it from a nurse who was not in the room.

For anything larger than a daily update — prognosis, a scan result, a decision about surgery — ask for a separate conversation with the consultant, in a room, with both parents present. That is a normal request and units book them routinely.

How long will this take

Nobody can give you a date on day one and you should be sceptical of anyone who tries. The rough guide staff use is your due date, but plenty of babies go home before it and some stay well past it. Discharge is a set of conditions — feeding, temperature, breathing, weight — not a calendar entry. What you can ask for is a weekly sense of direction: what is the thing we are waiting on this week.

Where to get support

Bliss produces the most complete UK-specific parent information for neonatal care and runs an online community for parents. In Ireland, the HSE publishes a parallel set of pages on neonatal and special care baby units. Your unit will also have a family support worker or psychologist — ask early rather than when you are at the end of what you can carry.
