Born at 30 Weeks

What 30 weeks usually looks like

Thirty weeks sits inside the World Health Organization's very preterm band, which runs from 28 to under 32 weeks. In practice it is often the gestation at which the emphasis shifts from rescuing to growing. Many babies born at 30 weeks need breathing support rather than a ventilator, tolerate handling reasonably well within days, and spend most of their admission on the unglamorous work of feeding and putting on weight.

That is a generalisation and your baby may not match it. Babies born at 30 weeks after growth restriction, with an infection, or without steroids having been given, can have a much harder first fortnight.

Breathing

Expect CPAP or nasal high flow rather than a ventilator in most cases. Bliss describes CPAP as air, with or without added oxygen, delivered through two thin prongs in the nose or a small mask, at slightly raised pressure to keep the lungs from collapsing between breaths. High flow is warm, humidified air through smaller prongs, used when a baby needs help but not that much pressure.

NICE guideline NG124 says teams should consider nasal CPAP or nasal high flow as the primary mode of non-invasive support, and that after initial stabilisation the target oxygen saturation is 91 to 95 per cent. The step down to low-flow oxygen and then to air usually happens over days to weeks, with reverses along the way.

Caffeine, and what it is doing

NG124 says to use caffeine citrate routinely in preterm babies born at or before 30 weeks, starting as early as possible and ideally before three days of age. Thirty weeks is the top of that band, so your baby will almost certainly be on it. It reduces pauses in breathing and the associated drops in heart rate. NG124 says to consider stopping it at 33 to 35 weeks corrected gestational age if the baby is stable, which is why it disappears from the chart weeks before you go home.

Lines, and then no lines

Nutrition starts intravenously. Bliss describes long lines as very fine tubes passed into one of the larger veins, used for nutrition and some medicines, and umbilical catheters as soft tubes placed into the blood vessels of the cord stump, mostly in the first few days. As milk volumes rise, the lines come out. The day the last line is removed is a genuinely good day and worth marking.

Eye screening applies at 30 weeks

Bliss states that babies born before 31 weeks' gestation, or under 1500g at birth, are screened for retinopathy of prematurity. Thirty weeks is inside that. Screening starts once the eyes have developed enough and repeats on a set schedule, often continuing after discharge as an outpatient appointment. Head ultrasound scans are also routine at this gestation.

Feeding is the main event

Tube feeds of expressed milk start early and build. Coordinating suck, swallow and breathe reliably enough to take a full feed by mouth is a developmental milestone that generally arrives between 32 and 34 weeks corrected, so a baby born at 30 weeks has two to four weeks of tube feeding ahead before that conversation starts. Sucking on a dummy while a tube feed runs is encouraged; NICE NG124 tells staff to explain to parents that non-nutritive sucking is beneficial, and that in tube-fed babies dummy use can shorten hospital stay.

From incubator to cot

Bliss explains that incubators keep babies warm and, when closed, hold in humidity so that moisture does not evaporate through very fine skin. The move to an open cot happens when your baby can hold their own temperature with a normal amount of clothing, which usually comes together with weight gain rather than at a fixed number of grams. It is one of the clearest signposts that the second half of the admission has started.

Which growth chart your baby gets

The Royal College of Paediatrics and Child Health publishes a neonatal and infant close monitoring chart designed for plotting very preterm infants from 23 weeks gestation to two years corrected age, using a date box system for gestational correction. A baby born at 30 weeks will normally be plotted on that chart rather than the standard one, and the centile you see on it has already been corrected. That is why a preterm baby's chart can look different from a friend's without anything being wrong.

What decides the going-home date

Not weight, and not a calendar. Breathing without support, holding temperature in an open cot, and taking all feeds without a tube. Bliss is straightforward that it is very hard to say early on how long a baby will need to stay, and that you will be involved in discharge planning as your baby gets closer. Ask at ward rounds which of the three is currently the limiting one. It gives you something concrete to watch, instead of a date that keeps moving.

The setbacks that are normal at 30 weeks

Three things startle parents at this gestation and are routine to the staff. A rise in breathing support after a good week is usually tiredness, a big feed, or the start of an infection screen — it is a rung, not a fall. A "septic screen" with blood tests and antibiotics started while cultures grow is a precaution taken quickly because infection moves fast in preterm babies, and antibiotics are often stopped at 48 hours when the cultures are clear. And a period of feed intolerance, where volumes are held or dropped back for a day, is the gut being cautious rather than something going wrong.

Bliss makes the same point about numbers generally: grades, stages and centiles were designed so clinicians could compare and decide, not to give parents a probability. If a figure frightens you, the question worth asking is what it changes about the plan for this week.

What you can do that nobody else can

Express, from the first hours if possible, because your milk is the one treatment only you can supply and it matters most in the babies whose guts are least mature. Do the cares. Ask to be at ward rounds. Ask for kangaroo care early — it does not have to wait for the wires to come off, and units routinely move ventilated babies for it with two staff. NICE NG124 tells neonatal teams to recognise parents as partners in their baby's care and to support them in that role, which means asking to be involved is not an imposition. It is the guideline.
