30 weeks - My baby's lungs and digestive tract are almost fully developed.
This week my baby continues to open and shut its eyes. Baby can probably see what's going on in utero, distinguish light from dark and even track a light source. Some researchers think baring your stomach to light stimulates visual development - but rest assured I will only be doing this in the privacy of my own garden when the sun is out!
To complete the picture, baby now has eyebrows and eyelashes.
