Your Baby This Week
Facial Movements & Growth
At week 16, your baby’s body continues to grow and become more proportional. The head is now more balanced with the rest of the body, while the arms and legs continue to lengthen.
Your baby’s nervous system is becoming more developed, allowing movements to become increasingly coordinated.
Facial Expressions
The developing facial muscles allow your baby to make small facial movements. Your baby may move the mouth, make sucking motions, and practice other early facial movements.
Developing Muscles & Bones
The muscles and bones continue to strengthen. Your baby can move the arms and legs more actively, although these movements may still be too subtle for you to notice.
More Active Every Day
Your baby is about the size of an avocado. The body is growing rapidly as the muscles, bones, and nervous system become more developed.
Your Body This Week
The second trimester may feel more comfortable for many people, although pregnancy symptoms can vary considerably.
Growing Belly
Your uterus continues to expand, and your pregnancy bump may become more noticeable as your baby grows.
Possible First Movements
Some people may begin noticing tiny movements around this stage, often described as fluttering or bubbles. Many others will not feel movement until later.
Skin Changes
Pregnancy hormones can cause increased pigmentation, including darker nipples or a darker line developing down the abdomen.
Back & Pelvic Discomfort
As your uterus grows and your center of gravity changes, you may begin experiencing mild back or pelvic discomfort.
