    No bones about it, you’re baby’s growing a skeleton.

    Your baby’s development

    The skeleton and intestines are taking shape.
    When you're 9 weeks pregnant, your baby's body parts and proportions continue to develop and change quickly:

    • Your baby grows to about 1 inch—about the length of an olive.
    • Beginning with the formation of cartilage, the skeleton begins to harden (ossification).
    • Fingers, toes, knees, and elbows develop.
    • Nipples and hair follicles form.
    • Intestinal system forms, including the pancreas, bile ducts, gallbladder, and anus. Intestines elongate.
    • Reproductive organs begin to develop internally.
    • Muscles develop and your baby may start to move — you might feel her movements in a few more weeks.

    Your nutrition and health

    Healthy habits should start now.
    Being pregnant gives you a new perspective on how your health habits can affect your body and your baby. There are many benefits to good nutrition during pregnancy.

    Good nutrition includes a healthy diet supplemented with a prenatal multivitamin as prescribed by your doctor. Starting now in your first trimester will help you maintain these habits throughout your pregnancy.

    Things to think about now

    “Want to hear the heartbeat?” “Uhhhh, yes please.”
    Your second doctor visit, which most often occurs sometime between the 8th and 12th weeks, might be shorter than your first prenatal visit, but it will include a check of many of the same vitals:

    • Weight
    • Blood pressure
    • Urine for sugar and protein
    • Uterus size
    • Height of fundus (the top of the uterus)
    • Your pregnancy questions or concerns

    Your doctor will use a special listening device called a Doppler to project the sounds of your baby's beating heart.

    What happens next week

    That brain is growing. Fast.
    Your baby graduates from embryo to fetus. And that little brain’s growing 250,000 neurons per minute.
