30 Weeks Pregnant

Your Baby is the Size of a Cucumber

Eyesight continues to develop, but can only respond to changes in light. Even after they're born, babies have around 20/400 vision. Another important step at around this time is that baby's bone marrow has taken over the production of red blood cells, as opposed to the tissue groups and spleen that were doing the job before. This is important because it means baby will be better able to thrive on its own in the real world. Also, until now the surface of your baby's brain was smooth. But its development has given it the wrinkled appearance we all recognize.

Changing hormones during pregnancy cause a lot of things, even the occurrence of very vivid, weird dreams.
