    Your baby’s development

    Alive and kicking!
    Your baby’s limbs are well-developed and she’s getting used to all of her parts. In week 20, your baby is moving around and you’re feeling it.

    Measuring about 6 inches, your baby is about the length of an eggplant, and weighs about half a pound.

    Your baby’s skin thickens and develops layers under the vernix, and her hair and nails continue to grow.

    Your nutrition and health

    Eating healthy now can mean a healthy baby later.
    The right nutrition choices now can benefit your baby both in the short term and in the long term. Research shows that nutrition in utero and during childhood can play a role in your baby’s health in many ways.

    Even though you’re 20 weeks into your pregnancy, you still have plenty of time to make healthy nutrition changes that can make a difference.

    Health benefits of good nutrition may include:

    • Brain and cognitive development
    • Growth and body composition
    • Metabolic programming
    • Cognitive and educational performance
    • Physical strength and immunity
    • Future risk for diabetes, obesity, heart disease, and high blood pressure

    Things to think about now

    Don’t forget to floss!
    Take care of your pearly whites and your gums. You are more susceptible to gingivitis (redness and swelling of the gums) while pregnant, so be consistent with brushing and flossing, and keep up with your routine dental visits.

    What happens next week

    The digestive system kicks in.
    By your 21st week of pregnancy, your baby’s digestive system is doing its thing, and his taste buds are beginning to develop.
