Buckle up folks, we're about to head into trimester two!
Your little womb tenant is getting bigger and smarter every day! Their skin is paper-thin and rather see-through, showing off all their shiny new functioning and still-developing organs.
Their sense of taste and smell are more developed and refined while their cozy amniotic sac continues to increase in size and mass and fill with more fluid.
As we embark on the second trimester, it's time for your manatee-to-alien-to-tiny-weird-human to evolve into monkey baby!
Little hairs, known as lanugo, will start to cover your baby's body this week, which will eventually be shed some time after birth.
Of all the trimesters, this one has been the most critical to ensuring your baby's development is on the right track.
If you've carefully adopted a healthy diet, continued to stay active, and made sure you're getting all the rest you need, you've got your little one set up for some spectacular growth and development in tri-two! Way to go, mama!
