Week 26 of Pregnancy: Your Baby Is the Size of a Kale Bunch

TL;DR

• Your baby is about 35.6 cm — the size of a bunch of kale.
• Baby's eyes are opening for the first time.
• You may be feeling increasingly ready to prepare for the birth.
• Consider signing up for a childbirth education class.

Your Baby This Week

At 35.6 cm, your baby is the size of a bunch of kale — and this week brings one of the most poetic milestones of pregnancy: your baby's eyes are opening for the first time. After being fused shut since early development, the eyelids are finally separating, and your baby can open and close their eyes.

Your baby can't see much yet — the womb is dark, and visual acuity won't develop fully until well after birth. But they can detect changes in light and may turn toward or away from a bright light source held against your belly. The eyes are typically blue or dark blue at this stage, regardless of what color they'll eventually be. Final eye color develops over the first year of life.

Brain activity is increasing dramatically. The brain is forming more complex patterns, and your baby's nervous system is mature enough to control some body functions. Your baby may respond to your touch on your belly, to the sound of your voice, and to changes in position.

The immune system is also developing. Your baby is receiving antibodies from you through the placenta, which will provide protection against infections in the first months of life. This passive immunity is one of many gifts you're giving your baby before they're even born.

Your Body This Week

The end of the second trimester is approaching, and you might be feeling a mix of emotions. The honeymoon trimester is drawing to a close, and the reality of the third trimester — and birth — is getting closer. It's normal to feel both excited and anxious.

Pelvic pressure might increase as your baby continues to grow and move lower. This can make activities like walking and climbing stairs more uncomfortable. Pelvic tilts and supportive belly bands can help distribute the weight.

Your blood pressure will be checked at every prenatal visit from now on. Preeclampsia — a condition involving high blood pressure during pregnancy — typically develops after 20 weeks and is most common in the third trimester. Your provider is monitoring for this, so keep your appointments.

You may notice that your breasts are changing again. Some people begin to leak colostrum — the thick, yellowish first milk — during the second or third trimester. This is normal and doesn't affect your ability to breastfeed later. Breast pads can help if leaking is bothersome.

Common Questions at Week 26

What should I know about childbirth education classes?

Childbirth education covers labor stages, pain management options (from breathing techniques to epidurals), when to go to the hospital, what to expect during delivery, and basic newborn care. Classes are offered by hospitals, birthing centers, and independent educators, both in-person and online. Most run 4-6 weeks, so starting now ensures you'll finish before your due date.

Is it normal to feel overwhelmed about the birth?

Completely normal. As birth gets closer, many people feel a mix of fear, excitement, and uncertainty. Learning about the process through a childbirth class can help transform anxiety into preparedness. Talking to your provider about your concerns and preferences can also help you feel more in control.

How do I choose a pediatrician?

Now is a good time to start interviewing pediatricians. Ask friends for recommendations, check that the practice accepts your insurance, and schedule meet-and-greet appointments. Questions to ask include: What are the office hours? How are after-hours concerns handled? What is the practice's approach to vaccinations?

This Week's Tip

Consider signing up for a childbirth education class if you haven't already. Knowledge is one of the best tools you can have going into labor and delivery. Understanding what your body will do, what your options are, and what to expect can significantly reduce fear and increase your confidence. Many classes also teach comfort measures, breathing techniques, and strategies for partners to provide support. Whether you take a traditional hospital class, an online course, or a specialized approach like Bradley Method or Lamaze, the preparation is worth it.
