Baby development

My eyes are still closed but they have grown larger and I have eyelashes and eyebrows.

I have begun storing subcutaneous tissue to help stay warm. Fat tissue is also important for metabolism, being an important source of energy. Even fetal fat has begun to envelop itself around me like a protective layer on my skin. Without the fat, I wouldn’t be able to survive in the amniotic fluid throughout a whole pregnancy.

The nails on my toes and fingers have grown out. I have also become more aware and responsive to sound. Did you know that it's never quiet inside your belly? I hear sounds from my mother's heart and intestines around the clock. It makes me feel safe.
