Child Protection Investigation Specialist (CPIS) Practice Exam

Which age range is associated with the ability to double birth weight?

1. 0-4 months

2. 4-8 months

3. 1-2 years

4. 2-3 years

The correct answer is: 0-4 months

The ability to double birth weight is typically seen in infants during the zero to four months age range. In the first few months of life, babies experience rapid growth and can gain weight quickly. By about four months, most infants have approximately doubled their birth weight, marking a significant milestone in their early growth and development. This double weight gain is a part of normal infant development and is influenced by factors such as nutrition, health, and genetics. During this age, infants are usually consuming breast milk or formula, which provides the necessary nutrients for this growth spurt. Understanding this developmental milestone is essential for a Child Protection Investigation Specialist, as significant deviations from expected growth patterns may indicate health or nutritional issues that require further investigation.
