Week 29 Pregnancy

Third Trimester

You are 29 weeks pregnant and in your third trimester. Your baby is about the size of a butternut squash. This week's key development: Getting Stronger Every Day. NHS note: Routine care.

Baby's Development

Your baby is about the size of a butternut squash.

Getting Stronger Every Day — Muscles and lungs are continuing to mature, and your baby is becoming more powerful in their movements — kicks and rolls can be quite forceful now. Their head may be turning toward your voice. Kick counts can be a reassuring daily practice from now on.

Routine care. Your midwife will continue to monitor your blood pressure and urine.

Practical Advice for Week 29

Nutrition

  • Continue vitamin D daily.
  • Eat calcium-rich foods to support your baby's rapidly hardening skeleton.
  • Constipation can worsen — eat high-fibre foods and drink plenty of water.
  • Small, frequent meals help manage heartburn and keep energy levels stable.

Exercise

  • Continue gentle exercise — walking, swimming, and prenatal yoga.
  • Pelvic floor exercises are more important than ever — they help with birth and recovery.
  • If heartburn worsens during exercise, try walking at a slower pace.
  • Practice breathing techniques from antenatal classes during exercise.

Wellbeing

  • Your baby's movements are getting stronger — kicks can be quite forceful now.
  • If movements decrease or change pattern, contact your maternity unit immediately.
  • Varicose veins may be more visible — compression stockings can help.
  • Take time each day to rest and connect with your baby.

Preparation

  • Routine midwife care — blood pressure, urine, and fundal height measurement.
  • Finalise your birth plan and share it with your birth partner.
  • Research what happens if you need an emergency caesarean — being informed reduces fear.
  • Start stocking your freezer with batch-cooked meals for after the birth.

Tip of the Week

Ensure you're getting enough calcium for your baby's hardening bones.
