Preteen is a term used to describe children between the stages of childhood and adolescence, typically ranging from ages 9 to 12. During this stage, children experience significant changes in their physical, cognitive, emotional, and social development. Girls especially are heading into puberty at an earlier age than they used to, with some starting as early as 9 years old. However, its important to note that the age range for preteens can vary, and some children may exhibit signs as early as 8 years old or as late as 13 years old. Its also worth noting that some children may act and think beyond their age, while others may act their age or younger. Parents should use their judgment based on how their preteen has responded in the past.
