A few important reminders for parents and caregivers of healthy infants
Remember to take your baby to regular well-child visits to help keep your child healthy and safe.
Though your baby is not more likely to need it, it is a good idea for everyone who cares for an infant to learn CPR. If you know CPR, you may also use it one day to help someone else in need. For classes near you, contact your child's doctor, the American Red Cross, the American Heart Association, or a national or local organization that offers training.
