This week

Everything is ready. Now you wait for each other.

  • A brain still sprinting
    The brain keeps growing at full speed, and it will not slow down for years after birth.
  • Shedding the coat
    Most of the lanugo and vernix are gone now, swallowed and stored in the gut as the first nappy's meconium.
  • Waiting for the signal
    Snug and low in the pelvis, your baby waits; labour usually starts between weeks 38 and 42.

Written against the NHS week-by-week guide. A picture, not a measurement: every baby grows at their own pace.

THIS WEEK’S QUESTION, FOR THE TWO OF YOU

“Anything you want to say to the baby on the eve of meeting them.”

Every Sunday, Syncry asks you both one question like this. You each answer in your own words, and the answers become your book.
