17 Week Old Baby Development

Your social butterfly is really spreading her wings now. Plus, postpartum exercises to get mama moving.

  • 17 Week Old Baby Milestones 👶

    Big things are happening in the social development department this week! Have you noticed that baby is mimicking your facial expressions lately? This is due mirror neurons (or cubelli neurons) firing in his brain. Try sticking out your tongue, then wait to see if baby will repeat this behavior. If he does, this is a sign that his mirror neurons are working—he’s observing your expression and performing these actions based on his observations. Here are some other things you can try to get those mirror neurons fired up:

    • Open and close your mouth several times
    • Blink your eyes slowly
    • Stick out your tongue
    • Lift your hand and keep it in front of her—see if she will try lifting his hand to meet yours
    • Smile
    • Frown
    • Put your hands together

    At this point, you may even notice him produce a little belly laugh when you tickle him. This is also due to his social development forming, giving you a reaction to an action. Just as he will laugh in reaction to your tickles, you may also notice him become upset or even cry when his play is interrupted. Don’t worry mama—this is totally normal. As your littles one’s social development strengthens, you will notice him stating his opinions much more (with both giggles and cries!).

    While it may be upsetting to hear your sweet baby cry in response to an unlikely event or occurrence, validate his feelings. (Want a refresher on the different meanings of crying? Click here.) It’s important that our babies know that we hear them and that we accept these feelings and emotions (even though it may be hard to!).

  • You at 17 Weeks Postpartum 👩

    Are you a mama who likes to move it-move it?? Now is the time to start thinking about moving that body. This isn’t about extreme weight loss but about keeping those endorphins up, and nourishing your body both inside and out.

    Did you know that light to moderate exercise, just 4-5 times a week can help:

    • Increase your energy levels
    • Make you feel happier!
    • Keep your skin looking radiant
    • Help boost your brain health and memory

    Who knew that something as simple as a brisk walk around the neighborhood a few times a week could provide so many benefits?!

    If motivation is lacking, try to find an exercise buddy to keep you inspired. If you feel you don’t have the time, just take 15 minutes at lunch or try this playground workout routine. Make a commitment to move a little more this week. #babysteps

    One quick note before we part: Before beginning an exercise routine, you may want to do a quick self-check for diastasis recti, or separation of the abdominal muscles. It’s a very common (up to two-third of mamas experience this!) result of pregnancy that’s very treatable—you just may need a more personalized exercise plan. Check out this article to learn more.

    I Know My Best Friend When I See Her

    Baby Week to Week 17 Mama Natural

    Everett and Vivian—two peas in a pod.

    We’re close to our siblings, and always knew we wanted at least two kids. But the universe seemed to have other plans. Infertility struggles made me fear we’d never have another baby—that my daughter would never have a sibling.

    Then two years later, our dreams became a reality.

    From the moment baby Everett came into this world, he was enamored with his sister Vivian. It was fitting that his first laugh was at her.

    As she was trying to entertain him by crawling back and forth under the arch of his play mat, he lit up. He squealed and let out a big belly laugh.

    Witnessing that interaction was literally a dream come true for me. That single moment filled my heart in ways I didn’t know was possible—an almost nauseating feeling of love watching my two babies laugh at each other. The two babies I had dreamt of for so long. — Jeannette G.
