To reduce your child's exposure to lead, get your child checked, have your home tested (especially if your home has paint in poor condition and was built before 1978), and fix any hazards you may have. Children's blood lead levels tend to increase rapidly from 6 to 12 months of age, and tend to peak at 18 to 24 months of age.
If your refrigerator is more than 10 years old, consider replacing it. New refrigerators today use half the energy of 10-year-old refrigerators and Energy Star labeled refrigerators are even more efficient. Some use 15% less energy than required by federal guidelines.
