Hey hey - we're at week 18!

Here's what's going on...

*the placenta is growing and nourishing the baby

*tiny air sacs called alveoli are forming in the lungs

*vocal cords are formed and the baby can cry, but doesn't make any sound

*features of the baby's heart - ventricles and chambers should be visible in an ultrasound

*the baby is about 5.59 inches and weighs 6.7 ounces
