Wearing a seatbelt
To avoid injuring your baby, your seat belt must be properly fastened. A lap belt should be secured below your belly and across your hips, so that it lies snugly over your pelvis (one of the strongest bones in your body). Never wear the belt across your belly — during a crash, the sudden jolt could cause your placenta to separate from your uterus.

Airline policies
You can fly on commercial airlines without restriction during your first and second trimester. During your third trimester you may run into some restrictions. Ticket agents won’t mention travel restrictions unless asked, so inquire about them when you book your seat. All airlines recommend you consult your physician before travel at any time during pregnancy.

Prepare for pit stops
You’ll probably be running to the bathroom more often than usual. When planning your car trip, remember to factor in plenty of time for frequent stops. Make it easy to answer nature’s call by wearing clothes that are quickly shed. Airplane facilities are cramped and public restrooms can be dirty, so when you find a clean, comfortable bathroom, use it.

Eating and drinking
Since your eating schedule may be disrupted on the road, it’s a good idea pack plenty of snacks, such as nuts, dried fruit, and crackers with low-fat cheese. Drinking extra fluids will help prevent water retention, too.

Enjoy yourself
Just because you’re pregnant doesn’t mean you can’t enjoy an active vacation. You can still continue with many of your normal activities, whether it’s hiking, or dining out. Use your common sense. If you feel overtired, overheated, or just uncomfortable, slow down or stop.
