    Your baby’s development

    Can you say weight gain?
    It’s the beginning of your final trimester and your baby continues to steadily add weight and important insulating fat layers to his body.

    At 30 weeks, he weighs about 3 pounds and is about 10.5 inches long from head to tush, or about the length of a bunch of celery. His legs and feet increase this measurement by many more inches.

    Here’s what else to expect in his development this week:

    • From now until week 37, your baby will gain an impressive ½ pound a week.
    • Your baby might be practicing breathing movements as he rhythmically moves his diaphragm. You may notice a slight twitching in your abdomen when this happens.
    • His brain continues to expand and develop; creating additional room that will support his learning and development throughout his lifetime.
    • Your baby’s brain can now regulate his body temperature, so he begins to lose the lanugo– the fine hair that has been covering his body for warmth.

    Your nutrition and health

    Keeping it healthy.
    You’re probably busy preparing for your baby’s arrival. So it’s reasonable that you’ll have less and less time for menu planning. If you find yourself reaching for convenience foods, keep a focus on the right portion size. Here are a few healthier substitutions to consider:

    Instead of This Try This
    Ice cream Frozen low-fat yogurt topped with granola, sliced berries, and a few dark chocolate shreds
    Potato Chips Baked potato chips, low-fat soy chips, or veggie chips
    Chocolate Trail mix with equal portions of nuts, seeds, dried fruit, and chocolate-covered raisins
    Cheeseburger Low-fat turkey burger or veggie burger, topped with avocado, tomato, and lettuce on a thin whole-wheat bun

    Things to think about now

    What’s that numbness or tingling?
    When you’re 30 weeks pregnant, it’s possible that your growing uterus might press on nerves in your legs and arms. This can cause your legs, toes, or arms to tingle. This is completely normal and it will disappear after your baby’s birth.
