Fetal development in pregnancy week 9: Congratulations! Your amazing growing baby has been accepted into to the fetus-club, a very exclusive and exiting new stage in their prenatal development. Basically, this means the little sweet pea has graduated from swimming embryo creature to a recognizable human being! This week in particular, the irises of their little eyes can function, but their eyelids remain fused shut for a while yet. Their external ears are formed and their inner ears are now filled with fluid—so your little one is already developing their sense of balance. Your baby's little swimmer legs are still relatively, although other bodily developments are going forward at a nice pace: their kidney is actually functioning now, which means they’ve started urinating. Here's a 3d ultrasound of what it might be looking like now.
