21Weeks Pregnant!

 

How big is my baby at 21 weeks?

How big is your baby? Switching from crown-to-rump to crown-to-heel length, he's 10½ inches long and weighs 11 to 12½ ounces, about the size of a large banana!

Baby's moving and sleeping

Until those uterine walls start closing in, however, there's plenty of space for twisting, turning and even an 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 noted 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 peanut 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 bodysurfing, or rather bellysurfing, you may have started feeling.
