PREGNANCY WEEK BY WEEK

16 weeks pregnant

About the size of an avocado

11.6cm and about 100 g

This week

Stretching, kicking, growing fast.

  • Coordinated moves
    Arms and legs now move together, coordinated by a fast-wiring nervous system.
  • A hard-working heart
    The heart pumps around 100 pints of blood a day, and it is barely the size of a nut.
  • Light through the dark
    The eyes can slowly move now, and they are becoming sensitive to light even with the lids still closed.

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

“It is starting to feel real. When did it first feel real to you?”

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