How Big is Your Baby at 16 Weeks?

Your baby is 4.6 inches and weighs 3.53 ounces this week. That’s about the size of a Hacky Sack.

Here’s what else to know when you’re 16 weeks pregnant:

Your Baby’s Development at 16 Weeks

If you’ve been talking to your baby, here’s an exciting development: they can start to hear you now! Here’s more about what’s happening with your baby’s development this week.

  • Developing taste buds: Your future foodie is starting to form taste buds. Tiny pores on the tongue have developed, and your baby is tasting and swallowing salty amniotic fluid as practice for future meals.
  • Toenails: Little nails are starting to sprout on baby’s toes. They should be fully grown around 34 weeks.
  • Umbilical cord: The umbilical cord is now fully developed. It normally has one vein and two arteries to keep baby growing and healthy, and is insulated by a thick goo called Wharton’s jelly. (Sounds gross but is necessary.)
  • Hearing: Teeny bones are developing in your baby’s ears, which means they can hear your voice. Talk away!

You have 168 days left of your pregnancy! That’s about as long as the regular NBA season.

Your Body: Pregnancy Symptoms at 16 Weeks

Now that you’re in the second trimester, you may notice some nice pregnancy side effects, like thicker hair, faster growing nails and some newfound or boosted cleavage, as milk ducts prep for baby’s first meals. Here’s what else may happening when you’re 16 weeks pregnant.

  • Pregnancy glow: Increases of blood flow and the hormone human chorionic gonadotropin really do make some pregnant women look dewy and fabulous.
  • Breakouts: Oh, the irony. The same factors that make some women glow can cause oily skin or acne during pregnancy instead. Run any acne products past your doc before using them; some aren’t safe for use during pregnancy.
  • Shortness of breath: With more progesterone, your body is tricking you into breathing more often and more deeply to get oxygen in, so you may feel winded from time to time. Also as the baby grows, they will push on your lungs and make it hard to take full, deep breaths. It’s OK to take breaks or go a little easier on yourself.
  • Stuffy nose: If you feel like your nose is stuffier lately, know this: pregnancy rhinitis—a runny or stuffy nose and no other symptoms—affects between 18% and 42% of pregnant women. An increase in estrogen makes the nasal passages swell, and in turn, more mucus is produced. A decongestant may help—ask your doc which are safe for you to take—but you can also try using a humidifier or shower steam, raising your head with an extra pillow while you sleep or saline nose drops or a spray to clear your nasal passages

Fun Fact

Your brain does change during pregnancy, but “pregnancy brain” has not been proven. The changes help you focus on your baby. That forgotten grocery list might be a side effect, though.

Your Life at 16 Weeks Pregnant

You’re four months along now! Whether time is flying or crawling, embrace your newfound pregnancy glow and use meditation to help you go with the flow. Omm…

  • Top tip: Go out to the movies, and we mean all out: We’re talking popcorn, Red Vines, Peanut M&Ms, the works. Bonus points if you make it a double feature. Why? Because you can and you’re finally up to it.
  • Shower thoughts: Before you decide on the specifics of your baby shower—who’s hosting and where—think about the kind of shower you hope to have. For some, nothing is more important than tradition. For others, the less traditional the better. Either way is okay! After all, it’s your day, so find a format that works for you. Whether it’s a virtual brunch with all the games or a socially distanced co-ed BBQ in the backyard, all that matters is you feel showered with love and support.
  • Gear to consider: The second trimester is when your boobs stop being sore and start getting bigger. If your bras are beginning to feel a bit snug, but you’re not quite ready to commit to nursing bras, opt for a bra extender. They’re a cheap way to give yourself some extra breathing room (literally!) before investing in new bras.
  • R&R: Meditation is a buzzword these days, and for good reason. A regular meditation practice can reduce stress, decrease anxiety and increase feelings of wellbeing, especially helpful during pregnancy, when you’re prone to worry. Still not sold? An abundance of apps—we like Headspace, Expectful and Calm—make it easy to get started. Even just a handful of minutes a day can make a difference.

Your 16 Weeks Pregnant Belly

At your next appointment, your OB or midwife will probably start measuring your fundal height. It’s basically the size of your bump, or the distance from your pubic bone to the top of your uterus. This measurement is a non-invasive way to make sure baby is growing properly and amniotic fluid levels are about right. (And we love non-invasive evaluations.) Your fundal height measurement should be equal to your pregnancy week, plus or minus two, in centimeters. So if it were to happen this week, you’d ideally be measuring between 14 and 18 centimeters. At week 20, you’ll probably measure 18 to 22 centimeters.

Your baby’s prepping for a growth spurt over the next few weeks, so don’t be surprised if your bump changes a lot too. You’ll feel baby’s movement more strongly and distinctly as time goes on too. If you’re not sure what you’re feeling just yet, rest assured that soon those kicks and jabs will be unmistakable.

16 Weeks Pregnant Checklist

  • Baby shower time is quickly approaching. First step: decide what kind of shower you want. Then, figure out who is going to host and where. Pick a date and help them with the guest list.
  • Schedule a self-date. See a matinee movie, get a spa treatment or just relax at home.
  • Try five minutes of meditation a day for one week. If you feel good, keep it going and add another few minutes each week, working your way up to 20 minutes.
  • Start sleeping on your side, ideally, your left (it helps get nutrients to baby via blood flow). Don’t panic if you wind up on your back, just flip onto your side and try again.
