Where babies roam, accidents often follow, but many can be avoided with a few precautions:

Car seats. Child should always ride in a properly installed car seat and only in the back seat. Do not substitute an infant seat for a car seat. The seat should face the rear until the child can sit up without help.

Poisoning. Store all medicines and household cleaning products out of reach. Use safety latches or, lower drawers and cupboards.

Drowning. A child can drown in only a few inches of water. Never leave children alone in a bath or near containers like pools and toilets.

Falls. Use stairway gates and window guards. Do not leave a baby unattended on surfaces above the floor, including changing tables and beds.

Fire prevention. Install smoke detectors and check batteries often. Dress baby in flame-retardant clothes.

Toys. Inspect toys carefully for small parts that can fit in a child’s mouth. Also look for sharp or rough edges.

Strollers. Do not hang bags from stroller handles. Always use seat belt and harness to keep baby secure.

Babies may have erratic sleeping patterns at first, but eventually they–and their exhausted parents–settle into a peaceful night’s rest:

New foods often bring out allergic reactions in young children. Avoid these highly allergic foods until your baby’s digestive system is ready:

Immunization of children in the United States is at a record high, protecting them from major diseases. Most shots are given during the first 18 months of life; check with your pediatrician regarding special care. A recommended schedule:

HEP B vaccine immunizes against a virus that can lead to chronic liver disease. Delivered in three doses, it should not cause any serious side effects.

A child may run a fever after the first shot of the DTP vaccine. If other less-com-mon reactions occur, like limpness or constant crying, notify your doctor.

HIB vaccine guards against bacteria that cause dangerous ailments like meningitis.

Sabin vaccine, given orally, is the most common immunization against polio.

MMR vaccine may cause a mild rash or fever a week after the injection.

The varicella vaccine should be given to babies who have not had chicken pox.
