At the 16th week of pregnancy, your baby has grown significantly and is approximately 11-12 cm and weighs around 100 grams. The limbs are well formed and the baby can move them freely, developing reflexes and more coordinated movements. The ears are in their final position and the baby can begin to hear sounds, such as the mother's heartbeat. The baby's skin is translucent, allowing the blood vessels underneath to be seen. This is an exciting period where the baby begins to interact more with her environment and continues to grow and develop rapidly.
The images and descriptions of your baby's development from week 1 to week 42 have been generated by artificial intelligence. Although they provide a close representation, they are not 100% accurate. To obtain accurate and personalized information about your baby's development, we recommend that you have an ultrasound and consult your doctor.
