Your baby can open their eyes
Your baby’s body is proportionally developed now, with a fully formed face, hair, eyebrows, and eyelashes.
This week, your baby will open their eyes for the first time [1]. They can now notice changes in lighting, and soon will begin to blink. For now, their eyes are blue, but soon they will change color according to their genes. Eye color may continue to change until the age of three [2].
Baby is stretching, kicking, and reacting to sounds, and their hands make grasping movements [3]. They can now move each arm and leg separately, so their movements can be directed towards all parts of the uterus.
Your baby’s lungs begin to produce surfactant, a liquid that protects the airways. Thanks to this substance, your baby will later learn to breathe independently [4].
If you are expecting twins
They can now look at each other for the first time! But what if it's dark? At this time they both have blue irises, but soon their eyes will change to the color determined by their genes. If you are having fraternal twins, then their eye color may not be the same [5].
What can be seen on the ultrasound
The picture shows a cross-section of the chest. The lungs in white, and the heart is the dark area in the middle of the image. The heart takes up almost a third of the chest. Four parts of the heart are visible: two atria and two ventricles, and the partitions between them.
