Week 20 Pregnancy: The Halfway Point

Twenty weeks. Halfway through pregnancy. This is a big moment—here is what you need to know.

What is Happening With Baby

Your baby is about the size of a banana now—roughly 10 inches long and weighing around 10 ounces.

• Baby can hear sounds now, including your voice
• They are developing sleep/wake cycles
• Vernix (a protective coating) is forming on the skin
• If you are having a girl, her uterus is fully formed

The Anatomy Scan

The 20-week ultrasound (anatomy scan) is the most detailed one you will get. The technician checks:

• Brain, heart, kidneys, and other organs
• Spine and limb development
• Placenta position
• Amniotic fluid levels
• And yes—you can usually find out the sex if you want to know

Tip: This appointment can take 45-60 minutes. Go with her. See your baby in detail. Ask questions.

How Mom Is Feeling

The second trimester is often called the "honeymoon phase" of pregnancy:

• Energy is usually better than the first trimester
• The bump is visible but not yet uncomfortable
• She might be feeling baby kicks regularly now
• Round ligament pain (sharp side pains) can happen as the uterus grows

What You Can Do

• Talk to the bump: Baby can hear you now. Read a book, sing badly, tell them about your day
• Start on the nursery: Good time to paint, build furniture, and set things up
• Plan a babymoon: Travel gets harder in the third trimester
• Celebrate: You made it to the halfway point. That is worth acknowledging
