Infants seem so portable: Just buckle 'em in the car seat or carrier and you're ready to hit the road, right? Well, not always. Negotiating even the simplest errands with a screaming newborn strapped to your chest can boost any new mom's stress level. Then there's the whole germ thing; when your baby is just weeks old, you want to stay away from crowded indoor areas where she can catch a cold or an infection. But out you must go -- older siblings require rides to school, the fridge needs stocking, and the infant herself has doctor appointments to keep. Then, too, after a month or so, you'll be itching to leave the house for a more substantial change of scenery. Before you shop the mall for a new outfit or make reservations for a nice dinner out, lessen the stress of traveling with your baby by checking out our expert advice. Then pack your diaper bag and take off.
