There certainly seems to be a boom in twins lately—at least according to the adorable photos our fans share with us. All we can say is, pretty soon your hands and your hearts will be full! And you're in good company. In 2013, there were 132,325 sets of twins born in the United States, according to the Centers for Disease Control and Prevention. That's roughly 3.4 percent of all births. Compare that to just 1.9 percent three decades ago.

But just because having twins is much more common, that doesn't mean it's gotten any easier. Technically, it puts you in the "high risk" category, according to the American Academy of Pediatrics' HealthyChildren.org. But they say there's no cause for alarm, just extra care.

The AAP recommends that you take the following steps:

1. Focus on nutrition, including vitamins like Folic acid and a healthy diet
2. Stay hydrated (water's the best option)
3. Listen to your body—and don't be afraid to pepper your doctor with questions
4. Be alert to rapid weight gain or headaches, which can be a sign of a condition called preeclampsia
5. Don't worry. Be happy! Your babies will thrive on your positive vibes.
