30 Weeks Pregnant!

 

How big is my baby at 30 weeks?

Your belly's increasing size is a definite clue that your baby is getting bigger every day — now he’s weighing in at about 3 pounds. He’ll be packing on weight at a rate of roughly half a pound per week for the next seven weeks.

Baby's brain is getting bigger

Also growing at a quick pace these days? Baby's brain. Until now, its surface was smooth — but now, your fetus' brain is taking on those characteristic grooves and indentations.

The reason for the different appearance: Those wrinkles allow for an increased amount of brain tissue — a necessary change as your baby prepares to develop street smarts for life outside your womb.

Lanugo is disappearing

Now that baby’s brain and new fat cells are regulating body temperature, the lanugo — that soft, downy hair covering your little bean's body — is beginning to disappear.

No need for that furry coat anymore! But you may see a few leftover strands of fur on your newborn's back and shoulders when she’s born.

Bone marrow is making red blood cells

Another big change at 30 weeks pregnant: Your baby's bone marrow has completely taken over production of red blood cells — before, tissue groups and then the spleen took care of producing the blood cells. This is an important step for your baby because it means he'll be better able to thrive on his own once he is born.
