As you get closer to your due date, your growing baby bump can start to feel like a homing beacon for unsolicited opinions. Do this. Eat that. Go there. With so much advice from friends, family, and random strangers, it can be tough to know what’s real and what’s nonsense. But while eating fish and taking that Zumba class is likely safe, there are a few things you should steer clear of, especially in your third trimester.

STRESS

Having a baby is stressful enough, but fretting too much can increase your blood pressure and put you at risk for pregnancy complications or going into labor too early. Babies born before 37 weeks are more likely to be underweight, have trouble breathing, and die from sudden infant death syndrome (SIDS). You want that bun in the oven to cook until it’s done (or about 39-40 weeks).

Ideally, you would avoid stressful things entirely, but if you can’t (because, you know, life) it’s important to find effective ways to manage stress, like exercising, meditation, and getting enough rest. If you need a little extra support, the Winnie Palmer Hospital for Women and Babies hosts a weekly emotional support group for new moms (including pregnant women) that is run by a licensed clinician.

DEHYDRATION

Typically, pregnant women need more fluids than other adults. It’s what cushions and feeds your baby. If you get dehydrated — especially in your third trimester — it can increase your chances of going into labor too early or having complications. Even so, it doesn’t take much to stay hydrated. All you have to do is take small sips throughout the day. And if you spend a lot of exercising or outside in the Florida heat, be sure to drink a little extra to replace the fluids lost by sweating.

ALCOHOL

Drinking during pregnancy is no joke. It’s linked to a laundry list of scary outcomes for both mom and baby, including the baby being born too small. While some people believe a small amount of alcohol — only once or twice on a full stomach — probably won’t harm the baby, both the Centers for Disease Control and Prevention and the American College of Obstetricians and Gynecologists say no amount of alcohol has been shown to be safe at any point during pregnancy. Considering the risks involved, it’s just not worth it.

SMOKING, VAPING, OR DRUGS

Consuming alcohol and drugs during pregnancy can pose serious dangers to new moms and babies — including nicotine found in tobacco and vaping products. Smoking makes your blood vessels narrow, cutting off valuable oxygen and nutrients to your growing baby and causing your chances of miscarrying or having a stillbirth to skyrocket. Additionally, about one in five babies born to moms who smoke during pregnancy has low birthweight. That’s huge.

Even if you don’t smoke or vape yourself, breathing in the smoke secondhand has been linked to giving birth to an underweight baby. So steer clear of places where smoke is common. And if you do smoke, vape, or use drugs, it’s important to quit right away. Talk to your doctor or visit resources like Tobacco Free Florida for help.

FLYING

A lot of things are different at 30,000 feet. The air is lighter. There’s less oxygen. And It’s easier to get dehydrated. But one of the greatest risks of flying in your third trimester is going into labor in the air without access to medical care. For that reason, many airlines forbid women from flying after a certain threshold (often 36 weeks) or require a doctor’s note to fly.

If you’ve had pregnancy complications or your doctor is worried you might go into labor early, he or she might recommend you avoid flights lasting longer than a couple of hours or stay grounded altogether in your third trimester. If you do end up flying, take precautions. Get up and walk around when the seatbelt light is off to keep your blood circulating. Drink plenty of water. And have a contingency plan in place by researching labor and delivery locations at your destination.
