The NHS publishes this figure for week 32, about the same length as a bunch of celery. It is an average from patient guidance rather than a measurement of any particular pregnancy, and the measurement basis changes at week 20 - see the note below the dates.

42.4 cm - a bunch of celery, by the NHS's reckoning, which is a comparison that says more about length than shape. Fat is being added steadily, and it is what will hold body temperature after birth. Most babies are head down by now, which obstetric notes call cephalic presentation, though a proportion are not and there is still time. Waddling has probably arrived, because the pelvis is doing something structurally awkward and the gait compensates. Tiredness is heavier. Here is the thing worth being clear about, because it causes needless anxiety: space in the uterus is reducing, but the rate of movement should not. The NHS is explicit that movements continue at the same rate right up to birth, and that a reduction is a reason to ring the maternity unit the same day - not to lie down with a cold drink and count for an hour first. The pattern may change in character as room runs out. The frequency should not. This is also the last week of the whooping cough window, which closes at 32 weeks in the standard schedule.

What the NHS describes this week

  • The NHS puts the foetus at around 42.4 cm from head to heel this week.
  • Fat is being added, which will help hold body temperature after birth.
  • Most babies are head down by this stage, described as cephalic presentation.

What happens around now

The NHS states that movements should continue at the same rate until birth even though space is reducing, and asks that any reduction be reported to a midwife or maternity unit the same day. The whooping cough vaccination window runs to week 32.

On the measurement. The NHS publishes a length for each week from 4 to 40. Up to week 19 it is measured head to bottom (crown to rump, the measurement a scan takes while the legs are curled). From week 20 it is measured head to heel, which is why the figure jumps from 15.3 cm at week 19 to 25.6 cm at week 20 - the baby did not grow 10 cm in a week, the ruler changed. The NHS states the change on its week 20 page.
