The fat accumulates — 3.1kg now, the characteristic weight of a newborn fully assembled. The lungs and brain continue their final maturation. The baby has been practising the skills of birth for months. And this week brings the culmination of something that has been building since hearing first came online at week 16, since voice recognition was established at week 30, since the palate formed at week 33: your baby already knows you. Completely.
This recognition is not sentimental metaphor. It is neurological fact, measurable in the first hours of life. The relationship that birth will appear to begin has already been in progress for thirty-eight weeks. When you hold them for the first time, they will not be meeting a stranger. You will be meeting each other — and they will already know their half of the story.
The midwife told me at thirty-eight weeks that the baby already knew my smell. I went home and sat with that for a long time. I thought about all the times I'd worried that I wasn't bonding enough in the pregnancy, that I'd feel like a stranger to my own baby. And here was the answer — they already knew me. Specifically, chemically, neurologically. The bond I was worried about building had been building itself all along, without my permission or effort. I couldn't have stopped it if I'd tried.
The 38-week appointment is primarily a monitoring check and a membrane sweep discussion. It is less information-dense than the 36-week appointment; most of the major decisions have been made. The focus now is on wellbeing, position, and supporting the onset of spontaneous labour.
Membrane sweep: if your cervix is favourable (soft, slightly dilated, the head engaged), a membrane sweep may be offered or performed at this appointment. It is your choice whether to accept. The evidence base is moderate — it increases the probability of labour beginning within 48 hours for people whose cervix is ready, but does not guarantee it. It can be uncomfortable; the degree varies significantly by individual cervical readiness. If your cervix is not yet ripe, a sweep may not be technically possible or may be offered again at 40 weeks. See the Scans, Tests & Antenatal Care guide for the full explanation of what a sweep involves.
Induction discussion: if you are approaching 40 weeks without spontaneous labour, the topic of induction will be introduced at this appointment. Induction is typically offered at 41 weeks in the UK; you will be given information about the process and given time to consider before any decision is required. See the Labour & Birth guide for what induction involves.
The instruction from week 37 continues and intensifies: rest. Stay close to home. Sleep is very difficult now — the pelvic pressure, the nocturnal urination, the Braxton Hicks, the inability to find a comfortable position — but the rest does not require unbroken sleep to be restorative. Lying down, resting the body, reducing activity and stimulation: all of this conserves the energy that labour will demand.
The affirmation for week 38 is the most important in the entire guide, and it deserves to be read rather than just cited: "You have carried, grown, and nourished this entire human being. Nothing you do after this will be more impressive." That is not hyperbole. It is an accurate assessment of what has happened over the past thirty-eight weeks. The body that began this pregnancy has built, from almost nothing, a complete human life. Whatever comes after the birth — however extraordinary — will be building on something that is already extraordinary.
Two weeks to the due date. Most first labours begin between 39 and 41 weeks; statistically, the due date itself is rarely the birth date. The two weeks ahead are most usefully spent in the way that this week has been: resting, staying close to home, trusting the body, and remaining genuinely attentive to the baby's movements without turning every sensation into an anxious analysis.
At thirty-eight weeks someone asked me how I was feeling and I said, truthfully, that I felt enormous, exhausted, and ready. But also that I felt like I was about to say goodbye to something I hadn't fully appreciated while I had it. The kicks, the intimacy of it, the knowledge of exactly where they were at every moment — none of that would exist in the same way once they arrived. I wanted to honour the pregnancy before it ended. I spent a lot of week thirty-eight doing that deliberately.
Saoirse names something that is rarely talked about but is commonly felt: the anticipatory grief for the pregnancy itself, even as the birth is eagerly awaited. The pregnancy is nearly over. The specific, extraordinary intimacy of carrying someone — knowing where they are every moment, feeling them move, having them entirely contained within the boundary of your body — is about to end. It is worth honouring that, alongside the excitement of what comes next.
At 38 weeks, every guide in the library is relevant. These are the ones most immediately useful right now — and the full topic library is always available.
The recognition detail this week applies to partners as well as to the birth parent. The baby has been hearing your voice through the womb — muffled, less present than the birth parent's, but heard and accumulating. The newborn they hand you in the delivery room will respond differently to your voice than to a stranger's. The weeks of talking to the bump, reading aloud, singing — all of it mattered. You are already a known presence.
The affirmation for week 38 — "Nothing you do after this will be more impressive" — applies to both of you. You have supported this pregnancy through nine months of physical and emotional demand. That support has been invisible and constant and genuinely important. It deserves acknowledgement, including from yourself.
- Be completely on call from now. Phone charged, close to home, nothing scheduled that can't be left immediately. Labour at 38 weeks is entirely normal. You need to be reachable and mobile from now until the birth.
- Read the early labour section of the Labour & Birth guide this week. Know the signs, the timing, when to call, when to go. Have the maternity triage number saved. Know the drive. Have petrol in the car.
- Create the conditions for rest. Your primary job for the next two weeks is making rest possible for your partner. Cook, manage the household, reduce noise and demands. The energy they conserve now is energy available for labour.
- Have the postnatal conversation. What does week one look like? Who is coming to help? What specifically are you taking on? These conversations are easier now than they will be at 2am on day three with a feeding baby who won't latch. Have them this week. See the Fourth Trimester guide for what to plan for.
Honour the pregnancy before it ends. Two weeks remain at most — possibly fewer. There are things about this particular closeness — the movements, the knowing, the carrying — that will not exist in the same form once the baby is born. This week's key action is not practical but human: notice it. Write about it. Let your partner feel the kicks. Sit quietly with the awareness of what is happening inside your body right now, and give it the attention it has earned.
At today's appointment, after the clinical checks:
The induction question is important to raise now, not when you are 41 weeks and physically exhausted and emotionally depleted. Understanding what induction involves — the prostaglandin gel or pessary, the timescales, the continuous monitoring, the pain relief available — before you are faced with a decision about it means you can think about it clearly and make a genuinely informed choice. See the Labour & Birth guide for the full induction section, and the Scans & Antenatal Care guide for the post-dates monitoring pathway.
