The age groups commonly used to categorize children are toddler (1 to 3 years) and child (4 to 12 years).
Here's a more detailed breakdown of age classifications often used for developmental stages:
- Infant: 0-1 year
- Toddler: 1-3 years
- Preschooler: 3-5 years
- School-aged Child: 6-12 years
- Adolescent/Teenager: 13-19 years
It's important to note that these are general guidelines, and individual children may develop at different rates. Furthermore, different fields (e.g., pediatrics, education, developmental psychology) might use slightly different age ranges for these categories. The term "child" is often broadly used to encompass individuals from infancy up to adolescence.
