Week 24 ยท scallion bunch

Fetal development

The fetus responds more to sound and light changes, and weight gain picks up.

Baby size comparison

Around week 24, baby is roughly comparable to a scallion bunch. Estimated size: about 14 inches and 27.6 ounces, with natural variation.

Common symptoms

  • Energy, appetite, sleep, and digestion may change.
  • Some people notice cramps, bloating, skin changes, or back discomfort.
  • Symptoms vary widely, and absence of a symptom does not always mean a problem.

Tests and appointments

  • Weeks 24-28: Gestational diabetes screening, CBC, and Rh antibody follow-up if needed.

Nutrition focus

  • Include protein, fiber-rich carbohydrates, colorful produce, and healthy fats.
  • Ask about iron, folic acid, iodine, vitamin D, choline, and omega-3 needs.
  • Follow local food-safety advice for fish, caffeine, unpasteurized foods, and supplements.

Warning signs

  • Call your care team for heavy bleeding, severe pain, fever, fainting, severe headache, vision changes, fluid leakage, or decreased fetal movement later in pregnancy.
  • Emergency symptoms should be handled urgently according to local medical guidance.
