Tweenager
A tween or tweenager is a person between the ages 10 to 12. In this stage of life, they are still developing. They can also be seen described with the term Preteens.
Timing of puberty
[change | change source]On average, girls begin puberty at ages 10 to 15; boys at ages 11 to 16.[1][2] Girls usually complete puberty by ages 15 to 17,[2][3][4] while boys usually complete puberty by ages 16 to 17.[2][3] The major landmark of puberty for females is menarche, the onset of menstruation. This usually occurs between ages 12 and 13;[5][6][7] for males, it is the first ejaculation, which occurs on average at age 15.[8]In the 21st century, the average age at which children, especially girls, reach puberty is lower compared to the 19th century, when it was 15 for girls and 16 for boys.[9] This can be due to improved nutrition resulting in rapid body growth, increased weight and fat deposition[10] or eating meat from animals which have been dosed up with estrogen.[11][12]
Sexual attraction to tweenagers or people going through puberty is called hebephilia.[13]
