Pregnancy Week 26 is the final week of the second trimester for many pregnancy calendars. Your baby continues to grow stronger and more active while important changes take place in the brain, lungs, nervous system and sensory organs.
You may notice that your baby's movements are becoming easier to recognize. Your growing uterus can also make everyday activities, sleeping and digestion more challenging.
This is a good time to continue focusing on your health, attending prenatal appointments and preparing gradually for the final trimester.
What Happens During Pregnancy Week 26?
During Week 26, your baby continues gaining weight and developing more body fat.
The brain is becoming increasingly complex, and the nervous system is helping your baby coordinate movements.
The lungs are continuing to mature, while the baby's hearing and other senses are developing further.
Your baby is also becoming more responsive to the environment inside the uterus.
How Big Is the Baby at Week 26?
Your baby is approximately the size of a zucchini, although exact measurements vary.
The baby continues gaining weight as more fat develops underneath the skin.
During the remaining weeks of pregnancy, growth and weight gain will become increasingly important.
Baby's Movement at Week 26
Your baby's movements may now be quite noticeable.
You may feel:
- Kicks
- Punches
- Rolling
- Stretching
- Turning
- Gentle tapping
- Sudden bursts of activity
Some babies are particularly active when the mother is resting.
Your baby will also have periods of sleep and rest.
As pregnancy progresses, you will gradually become familiar with your baby's normal movement pattern.
Why Does My Baby Move More at Night?
Many pregnant women notice more movement when they are resting in the evening.
During the day, walking and other activities can make movements less noticeable.
When you lie down quietly, you may simply become more aware of your baby's movements.
This does not necessarily mean that your baby is only active at night.
Baby's Brain Development
The brain continues developing rapidly during Week 26.
Nerve connections are becoming increasingly complex, supporting movement, sensory processing and other developing functions.
The nervous system will continue maturing throughout pregnancy and after birth.
Baby's Developing Senses
Your baby's senses continue developing.
Hearing is becoming more mature, and your baby can hear sounds from inside your body.
Your baby may also respond to louder sounds from outside the uterus.
Touch and other sensory systems are continuing to develop as well.
Talking, reading or singing to your baby can be a pleasant bonding activity.
Baby's Eyes
The structures of the eyes continue developing.
Your baby's eyelids have developed, and the eyes are becoming increasingly prepared for vision after birth.
Although the baby's vision is still immature, eye development continues throughout the remainder of pregnancy.
Baby's Lungs
The lungs continue their gradual maturation.
The structures necessary for breathing are developing, but the lungs are still immature.
Your baby's lungs will continue developing throughout the third trimester.
Baby's Skin and Body Fat
Your baby is gradually developing more body fat.
This fat helps give the body a fuller appearance and will eventually help regulate body temperature after birth.
The skin remains protected by vernix caseosa, while fine hair called lanugo may still cover parts of the body.

- Heartburn

Your Growing Baby Bump

You may also find that certain movements, such as bending down or standing for long periods, are becoming less comfortable.
Take breaks when needed and avoid pushing yourself beyond your comfort level.
