Classes in basic infant cardiopulmonary resuscitation are beneficial for anyone who'll take care of your baby -- not just Mom and Dad. Unintentional choking and suffocation are the leading causes of all injury deaths for infants under age 1, according to the American Heart Association. It's worth taking the two- to four-hour course to learn how to recognize when a baby needs rescue breathing, start CPR, and care for an infant who's choking. Even if you're on your second or third child and have taken the course before, it's a good idea to take a refresher class or at least get up-to-date CPR instructions and information from the American Red Cross or the American Heart Association. "I have former students who've had to use the techniques they learned in class," says Lisa Gatto, certified CPR instructor at Isis Maternity in Needham, Massachusetts. "But, most important, it gives caregivers confidence that they'll know how to help the baby in case of an emergency." Find a local course at redcross.org.
