Little lungs are getting ready for oxygen
Week 17: Your baby is getting ready for breathing and growing
Between the 17th week and 20th week of pregnancy, your babyís lungs are getting close to being able to function, while layers of brown fat start to grow.
- Right now, your baby is about 4-1/2 to 5-1/2 inches long, or about the length of a large orange.
- Little hiccups continue, and you might feel them.
- When youíre around 17 weeks pregnant, a necessary fat called brown fat develops under your baby's skin. This will help keep her warm after birth. Later in your pregnancy, your baby will develop additional layers of fat.
- Air passages in your baby's lungs finish branching.
- By your 17th week of pregnancy, your baby's lungs prepare to take in oxygen.

Don't forget about vitamin B12
Vitamin B12 is an essential B vitamin involved in the formation of all body tissues. Vitamin B12 is important for correct genetic code replication in cells. Vitamin B12 is only found in foods of animal origin, so vegetarians should make sure they are getting sufficient amounts from food sources that are allowable under their dietary guidelines, or from proper supplementation.
The Recommended Daily Allowance (RDA) of vitamin B12 for pregnant women is 2.6 mcg, and 2.8 mcg during lactation.
Here is a list of common foods that contain vitamin B12:
|Food:||Amount:||Vitamin B12 Amount:|
|Milk||8 oz||0.9 mcg|
|Yogurt||8 oz||0.9 mcg|
|Kellogg's Special K® cereal||1 cup||6 mcg|
|Eggs||1 egg||0.5 mcg|
|RED STAR® Nutritional Yeast
Vegetarian Support Formula
|1 tablespoon||4 mcg|
Women who do not consume meat or dairy foods should discuss with their health care professional the need for a supplemental source of vitamin B12 during pregnancy, such as a prenatal vitamin that contains 100% of the RDA for vitamin B12.
