How big is baby?

Your baby is the size of a papaya. Her lungs are developing rapidly, and they will begin making a protein called surfactant, which will help her breathe independently once she's born.

Baby's Length: 10.94in.
Baby's Weight: 15.17oz.

Baby's Development

Your baby's previously see-through skin will now become opaque. However, it will remain wrinkly, red, and covered in vernix until more fat helps to fill it out. Also this week, he's fine-tuning his sense of touch (thanks to maturing brain cells and nerve endings). Your baby may experiment with these newfound skills by feeling his face or anything else he can get his hands on. This week, your baby's eyebrows start growing and hair will start sprouting on the scalp, but this varies — your baby may grow a thick head of dark hair or he may enter the world bald.

Baby Week 22

From head to foot, your fetus is about 11 inches with a weight of just under 1 pound.The brain is growing and starting to develop more complex neurological connections.The developing fetus can now hear your heart beat, your stomach churn, and hear the sound of your voice.Just below newly formed eyebrows and beneath newly formed eyelids are more developed eyes that continue to sense light. If given the chance the fetus might even turn away from bright lights.

What Week 22 of Your Pregnancy is Really Like

Mom's changing body

Feeling dizzy? This is another normal pregnancy side effect, and it's due to the fact that your blood pressure has dropped. Your blood can't move as fast as it used to, so you may feel lightheaded when you stand up or after standing for a long period of time. You're probably enjoying the benefits of pregnancy hormones now in the form of thicker hair and stronger nails, but along with the gorgeous locks, you may start to notice a few unwanted hairs. Stick to plucking, waxing and shaving for removal — bleaches and depilatories contain unsafe chemicals.

Sometimes Being Pregnant Sucks (And It's OK)

It's Week 22 and you've been pregnant for a while—you're over the hump, but you still have a trimester and a third to go. While pregnancy is a time for glowing, planning and getting excited for the baby-­to-­be, it can sometimes be a bummer: Sleepless nights trying to stay in the "right" position (Why is it that you always loved sleeping on your left side until now, when you're supposed to???), heartburn, a general sense of anxiety you can't shake, mood swings. Sometimes pregnancy blows—and it's OK to recognize that. Today we'll talk about why you really don't have to LOVE being pregnant all the time.
