A normal blood pressure reading for a 3-year-old typically ranges from 90/40 to 110/60. The reading of 90/40 falls within the acceptable range for a child of this age, indicating that the heart and blood vessels are functioning normally. Blood pressure in children can vary based on height, weight, and general health, but pediatric guidelines generally indicate that readings closer to the lower end of the scale are often considered normal.

The other values offered do not represent typical ranges for this age group. For example, a reading of 100/60 is slightly elevated for a young child, while 80/50 and 85/35 are on the lower edge or below what is generally accepted for healthy blood pressure in a 3-year-old, which may require further evaluation. Monitoring these readings is essential, as maintaining an optimal blood pressure range supports overall health and development in children.
