Your Baby This Week
Rapid Growth & Development
At week 12, your baby has grown considerably since the earliest weeks of pregnancy. The head is still relatively large compared with the body, but the body is becoming longer and more proportional.
The basic structures of the major organs have formed, and they will continue to mature and become more functional throughout the rest of pregnancy.
Facial Features Become Clearer
The eyes, nose, mouth, and ears continue developing. The facial features are becoming more recognizable as the baby’s head and face mature.
Developing Reflexes
Your baby can make small movements and may begin making reflexive movements, although these movements are still too subtle for you to feel.
Growing Stronger
Your baby is about the size of a lime. The body is becoming more proportional as the organs, nervous system, and limbs continue to develop.
