Suitable for boys and girls of any age, it presents an excellent introduction to puberty for the younger reader as well as the late starter. So That's What's Happening! covers the physical changes of puberty including why people change from child to adult, when & how the changes begin, hormones, changes to body shapes and sizes for boys and girls, growing hair, changing voices, hygiene, pimples, the male and female reproductive systems and how they work, internal body changes, eggs, sperm and how they meet, periods, erections, wet dreams, keeping healthy, moods, feelings, choices and even getting along with parents.
