Your Twin Babies at 27 Weeks Pregnant

Right now, your twins are getting pretty damn big. They’re 14 to 15 inches long, and can weigh up to 2 whole pounds. That’s as big as your average sized head of lettuce. Your twins might be slightly smaller than this, but not by that much. No wonder you’re getting so big, right?

It’s not just size that’s increasing. Their awareness of the world is going up and up. Little eyes will be opening and closing, and they’ll react to light and sound from the outside world, too.

They’ll be far more able to respond to all this sudden stimulus, too, turning heads away from light sources to sleep, with a sleep schedule that’s getting more and more regular, and even sucking their thumbs for comfort!

If they haven’t already, sexual organs will be developing soon, with boys testes making the journey down to where they’ll eventually end up, and the girls clitoris developing and becoming prominent.

Twin Pregnancy Symptoms at 27 Weeks

You’re still going to be feeling the same sort of symptoms this week, and they’re steadily going to get stronger. On the upside, you’re probably used to this by now, and you’ve got your own strategies for dealing with it all.

  • Braxton Hicks contractions: These will still be going on, and might last as long as two minutes at a time. Expect them to get more frequent, and last a little longer, as you go through the coming weeks. Remember that they’re nothing to worry about, unless they ever become irregular, painful, or last longer than a few minutes.
  • Leg and foot cramps: Hydration is a massive help to deal with cramping, and if you’re suffering, make sure you stretch your legs often, as if you’re on a plane for DVT.
  • Backache: You might also have an aching back. Especially as you’re carrying twins, and the increased weight is far more than your body is used to. Having to sleep in a different position than you’re probably used to doesn’t help, either, so if you’re struggling, keep yourself supported and comfortable throughout the day, and at night, consider sleeping propped up with multiple pillows, or a dedicated pregnancy pillow.
  • Constipation and haemorrhoids: Your twins put a lot of pressure on you down there, and it can make going to the loo a lot more difficult than you might be used to. Eat a balanced diet, make sure you’re getting enough water, and if you have to, take medication that’s been recommended to you by your doctor. Don’t worry though, girlies, this issue should clear up once you’ve had your kids.
  • Shortness of breath: Your twins are crowding out space in your abdomen right now, making it hard for your lungs to expand to full capacity. If you get a little short of breath, it’s okay to take a break sometimes, so don’t feel bad about having to sit down for half a minute occasionally.
  • Bladder ‘issues’: It’s an uncomfortable thought, (and a more uncomfortable experience) but all that pressure on your bladder from carrying two babies can cause you to accidentally pee a little bit when you sneeze, yawn, or even just go up stairs. To deal with this, try not to walk around with a full bladder, and if you have to, wear a pantyliner.

27 Weeks Ultrasound Twins

It’s doubtful you’ll be having an ultrasound this week, but as of next week, expect them to become a lot more frequent. As often as two a month. So relax, and get used to them.

Things to Do This Week for a Healthy Pregnancy

  • Set up next week’s ultrasound appointment. Even if you’ve booked it, plan a few things that you can do in the waiting room. I’ve always found it’s an ideal time to plan things like your baby shower.
  • You’re carrying twins. That means that you’re at an increased chance of early delivery. From next week, that chance shoots up, so if you’re worried, or you’ve had any indication from your doctor that you might be likely to have an early delivery, talk to your healthcare professionals and see what you can do about it
  • It’s also good to familiarise yourself with the signs of early labor, especially if you’re having frequency Braxton Hicks contractions

Let’s talk about being on the go with your twins. It gets complicated fast. You need gear which can not only provide value to your infants, but also make your life easier.

  • A car seat. This is obviously a must have. It’s worth getting one which you can use beyond the infancy period. This one will more than satisfy.
  • Having a diaper bag is a key component to any outing. This is our favorite for twins.
  • Why not set up your Baby Registry?
  • A stroller is another must have. In the first few months it is recommended to use a frame stroller like this one, which you can use in combination with a car seat. Makes life easier.
