WEEK 12

Fetal development in pregnancy week 12

Despite being a super-dooper grower, your little Einstein’s body is still far behind the astonishing growth of their amazing brain. In other words, your baby is still a bobble-head, as their massive noggin' comprises 30% of their entire body mass!

Bobblehead aside, your little lollipop's neck is up to the challenge and straightening out quite nicely as can be seen by their little chin lifting off of the chest.

Your baby is also actively rehearsing “breathing” by inhaling and exhaling amniotic fluid (ew!) to prepare the lungs for future air respiration.

The big news: your little poop-n-pee factory is now up and running!

Don't worry, most of the liquid waste wends it way down to your bladder, just adding to your million-times-a-day rides on the porcelain pony.

The solid waste - aka their first baby poop is just starting to build up in their intestine (it's a super-slow build-up, since it's all derived from liquid blood) in preparation for that tarry black meconium newborn poop.

Along with all the lovely poop-n-pee talk, we thought you'd like to know that your baby now pees into their amniotic sac and then inhales it through their mouth and nose.

YUCK! Not to worry, their urine is completely sterile and harmless, no matter how gross it seems.
