Physical Development
By 27 weeks, your baby is around 14.8 inches long and weighs about 2 pounds. Your baby’s eyes are now fully formed and can see light, although they won’t be able to focus on objects just yet. Your baby’s lungs are also continuing to mature, and he or she is practicing breathing movements in preparation for life outside the womb.
You may start to notice that your baby has periods of activity and rest throughout the day. This is because your baby is developing regular sleep patterns, with periods of REM (rapid eye movement) and non-REM sleep. Your baby’s movements may also become more coordinated, with less jerky or random movements and more purposeful stretching and kicking.
Brain Development
Your baby’s brain is growing at a rapid pace, with new neurons forming at a rate of up to 250,000 per minute. This means that your baby’s brain is now at its most active and flexible stage of development, and can adapt to new experiences and stimuli in the environment.
You can help support your baby’s brain development by talking, reading, and singing to your baby. This will help your baby learn new sounds and language patterns, and can even help stimulate brain growth.
Social Development
Although your baby isn’t yet born, he or she is already developing social skills that will be important later in life. By 27 weeks, your baby can recognize your voice and may even respond to it by moving or kicking. Your baby is also learning to differentiate between different sounds and voices, and can tell the difference between your voice and other sounds in the environment.
Frequently Asked Questions

When can my baby hear me?
Your baby’s ears are developing from around 8 weeks of pregnancy, but it’s not until around 18 weeks that your baby can start to hear sounds in the womb. By 27 weeks, your baby can hear your voice and may even respond to it by moving or kicking.
What should I be eating during pregnancy?
It’s important to eat a healthy, balanced diet during pregnancy to support your baby’s growth and development. This includes plenty of fruits and vegetables, lean protein, and whole grains. You should also make sure to get enough calcium and iron, as these are important nutrients for your baby’s bone and blood development.
What should I be doing to prepare for my baby’s arrival?
As your due date approaches, there are a few things you can do to prepare for your baby’s arrival. This includes setting up a nursery, buying baby clothes and supplies, and creating a birth plan with your healthcare provider. You may also want to take a childbirth education class to learn more about the birthing process and how to care for your newborn.
When should I start looking for a pediatrician?
It’s a good idea to start looking for a pediatrician during your second trimester, so that you have plenty of time to find a provider who is a good fit for your family. You can ask for recommendations from friends and family, or do your own research online or through your healthcare provider.
What should I expect during labor and delivery?
Every labor and delivery is different, but some common signs of labor include contractions, water breaking, and cervical dilation. It’s important to talk to your healthcare provider about your birth plan and any pain management options that may be available to you. Remember to stay calm and focused, and know that you have a team of healthcare providers who are there to support you every step of the way.
