Week 23

Wednesday, January 07, 2009

Nothing too eventful happened this week, so this blog will just be an update on the pregnancy.

Your baby continues to grow and develop inside of you. He is now about the size of a mango, measuring 11 inches long and weighing about 1 pound. In the coming weeks your baby will continue to grow and mature a fast rate, gaining about 6 ounces of weight a week.The body of your baby is getting plumper but his skin is still fairly wrinkled due to the lack of subcutaneous fat. His skin is still wrinkled, but the pigments that will give his skin color are currently being deposited.

By week 23, the blood vessels in his lungs, important for breathing outside the womb, are developing. His lips are becoming more distinct, and his eyes continue to develop, though they still lack color. Also, by this week, the bones in his middle ear start to harden.

He's starting to drink the amniotic fluid he's floating in, and his digestive system is mature enough to absorb nutrients. And not only is your baby starting to drink and taste, but all of his sensory systems are maturing as well. Your baby's face and body is looking more and more like those of an infant, the bones of his inner ear are beginning to harden and his pancreas is developing (the pancreas is very important in the production of insulin). Your baby's fingernails are almost fully formed and the lanugo (fine hair) that covers his body is getting darker. Your baby continues to grow in preparation for the journey of birth. You baby is now more than 11 inches long and weighs over a pound.

Coming Soon: Week 24

    I love how they always compare the size of the fetus to a fruit or a vegetable. My husband just couldn't relate...he needed a fast food comparison, like "This week, your baby is the size of a quarter pounder with cheese!"

    Glad things are going well with your pregnancy :)
