WOOHOO! Your amazing growing baby has been accepted into to the fetus-club - an exclusive 7 month stage in their prenatal development.
Basically, this means your little sweet pea has graduated from swimming embryo alien creature to a weird-looking little tiny human being! This week in particular, the irises of their little eyes can function, but (frustratingly for them?) their eyelids will be fusing shut until around the 26th week.
Their external ears are formed and their inner ears are now filled with fluid - which allows your little womb gymnast to begin developing their sense of balance.
Their little swimmer legs are still relatively small, although other bodily developments are going forward at a nice pace: their kidney is actually functioning now, which means they're also officially able to urinate. This newly developed pee-trick might seem cute or something, but just wait till you have to start changing diapers!
