PREGNANCY WEEK BY WEEK

17 weeks pregnant

About the size of a pear

13cm and about 140 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

“What names are you drawn to, and what do they mean 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.
