Baby's moving and sleeping
Until those uterine walls start closing in, however, there's plenty of space for twisting, turning, and even doing the occasional somersault — so that's what you were feeling last night!
With all that belly dancing going on, it's hard to believe your baby is getting any shut-eye at all. But believe it or not, your fetus sleeps as much as a newborn. Now if only you could get some sleep yourself!
Baby's taste buds develop
Speaking of milestones, whatever you eat this week, there's a good chance your baby will taste it too. That's because when you're 21 weeks pregnant, your baby swallows a bit of amniotic fluid each day — not only for nutrition and hydration, but also to practice swallowing and digesting, skills he'll need as soon as he arrives in your arms.
And keep this in mind: The taste of the amniotic fluid differs from day to day depending on what you've eaten — spicy enchilada one day, sweet banana the next. That smorgasbord of flavors won't be lost on your baby since your little one has very developed taste buds already.
In fact, researchers have found that babies who were exposed to certain tastes in utero via the amniotic fluid were more eager to eat foods with those same tastes after birth. Want your cutie to eat his broccoli later? Eat yours now!
Baby's getting coordinated
Your little action figure is able to choreograph Matrix-like moves at 21 weeks pregnant. Arms and legs are finally in proportion, neurons are now connected between the brain and muscles, and cartilage throughout the body is turning to bone.
All these upgrades combine to give your baby more control over limb movements, which explains all that kicking, stretching, and body surfing you may have started feeling.
The Mutlu Anne app is with you every step of the way on your pregnancy journey.

This Week's Highlights

He's got the moves
Your baby's arms and legs are in proportion this week and his movements are now much more coordinated. Also, notice a jump in baby's length this week? Up until now, we've been measuring from crown to rump, but now we start to measure from crown to heel, which explains why he suddenly "grew" so much.

More blood cells
Your baby-to-be's liver and spleen have been working hard producing blood cells, but now the bone marrow is developed enough to help too.

Baby's drinking
While the placenta is still #1 when it comes to nourishment, now your baby takes in small amounts of amniotic fluid, too.
