A. "I should place a cool mist humidifier in his room.": Children with Down Syndrome often have narrow nasal passages and a tendency toward respiratory infections. A cool mist humidifier helps keep the airways moist, reducing irritation and easing breathing.
B. "I should expect him to have frequent diarrhea.": Diarrhea is not a common symptom associated with Down Syndrome; constipation is more frequent due to low muscle tone.
C. "I should expect him to grow faster in length than other infants.": Infants with Down Syndrome tend to have slower growth rates and may not reach the same length or weight milestones as peers.
D. "I should avoid the use of lotion on his skin.": Infants with Down Syndrome often have dry, sensitive skin, and the use of lotion is encouraged to prevent dryness and cracking.
