Backpack carrier basics

A backpack carrier lets you travel in ways you never thought possible with a baby, including rugged, backcountry hiking and snow shoeing. But it can also be used for smaller, less exotic trips to the mall, the zoo, or even Disney World. Thinking about getting a carrier? Here are five things to keep in mind before and while you're shopping.

Hold off on this purchase. If your baby is a newborn, there's no need to buy a carrier just yet. Backpack carriers are intended for children old enough to sit up independently--usually at least 6 months old--up to 40 pounds, plus 10 pounds of gear, depending on the model. The weight of the pack itself can add another 4 to 7 pounds to your load, so consider that when choosing a pack. A heavy carrier might make it more difficult to carry your child.

Bring your baby. When your baby is about 6 months old, take her with you when you're shopping for a backpack carrier and if your child is game, do test runs in the store to try on carriers for size, fit and comfort. If you expect to be wearing them during colder months, try a backpack with a coat on and your child.

Practice, practice. With the help of a knowledgeable salesperson, try putting the carrier on and taking it off. Have your spouse do likewise to make sure it fits you both comfortably. If you and your spouse will be switching the pack back and forth, adjust the straps to fit your torso so you can see if it's easy to do (or not). Walk with the backpack to be sure the frame doesn't hit the back of your head, that it's not too long for your height, that the straps fit properly so they won't slip off your shoulders, and that the frame doesn't start to dig into your lower back after a few minutes. You should be able to walk comfortably with your arms at your sides and carrier directions should be easy to follow.

Look for a snug-fitting safety harness. The safest backpack carriers have a harness for the child that connects the shoulder straps with the crotch, torso, and hip restraints for a snug fit.

Be wary of second-hand equipment. A backpack carrier is something many parents pick up at tag sales. If you decide to buy used, check for recalled brands at the www.cpsc.gov. Inspect carriers for excessive wear, which can dangerously weaken straps and seams.
