Sunflower, cut stem

50.1 cm (19.7 in)head to heel

At about 50.7 cm from head to heel, your baby is close in length to a Sunflower, cut stem (~50 cm)—the bright icon saved for near the end.

This week, inside

A tougher outer layer of skin is developing to protect internal organs and support temperature control. Vernix may still coat the skin at birth, or it may be mostly gone.

What you might be noticing

  • More practice tightenings. Braxton Hicks tightenings may be frequent while remaining painless.
  • Sleep and back. sleep difficulties and backache may continue.
  • Digestion. indigestion, bloating, constipation, or piles can remain part of the week.

Small things that help

Put the final practical details somewhere visible, then give yourself permission not to rehearse them. Save one photo of this ordinary, extraordinary in-between.
