Day 50

The surface of the baby's brain is now beginning to develop the rounds and fissures characteristic of humans. The upper lip is fully formed. Primary ossification centers are appearing in the long bones. These centers direct the replacement of cartilage by bone. The ossification process always starts in the upper arms, where the first true bone cells will replace the cartilage. If the baby is a girl, the clitoris is beginning to form (from the same tissue that the male penis develops from). By this time, the critical period for the baby's heart development has ended. The heart will continue to grow and develop, but not at such a fast pace.

For your information...The baby's heart has been beating strongly. The stomach can produce some digestive juices, the liver can manufacture blood cells, and the kidneys can extract some waste products (uric acid) from the baby's blood stream.

Food Facts...During pregnancy, take car to safeguard the nutritional value of the foods you eat. Baking a vegetable in its skin preserves most of its food value; microwaving vegetable skins on is likewise beneficial as is grilling, provided a little oil is used.

This has been another installment from "The Pregnancy Journal" by A. Christine Harris, Ph. D.

Love these updates.
But, don't forget to tell us how you're doing... how you're feeling... craving weird things... etc.
Love you! XO Mom

(And Alana is concerned - like me, that you're still snowboarding... call the doc, okay? If he says it's still permissable, we'll rest easier...) ;-)

I haven't even gone snowboarding since the last doctor appointment. I even found out the other day that my boss aggressively skied until she was 7 months pregnant! BUT, if it'll make you feel better, I'll call the doc before I go out again. I don't see that happening until at least next weekend though. :-)
