An illustrated cabbage

By week 30 your baby is making their own red blood cells, and the fine hair covering their body is starting to shed.

Your baby this week

Blood
Bone marrow has taken over making red blood cells.
Lanugo
The fine hair on the body is starting to fall away.
Space
Your baby still has room to move, and should keep moving as much as before.

What you might notice

  • Trouble sleeping, and needing more pillows.
  • Mood changes as the end gets closer. It's normal to feel excited and anxious at once.
  • Breathlessness and heartburn.
  • Swelling in your feet and ankles.

Call your midwife, doctor or maternity unit today if

  • Your face, hands or feet swell suddenly, or you have a bad headache or blurred vision
  • You have bleeding, fluid leaking, or regular tightenings or period-like cramps
  • Your baby's movements have slowed down or changed
  • You have strong itching, especially on your hands and feet

Any time of day or night. You will never be a nuisance for calling.
