It is a normal part of child development to exhibit a range of sexualized behaviours. Psychosexual development begins in infancy and early childhood with an interest in exploring one’s own body then, during latency, moves to a curiosity about the bodies of others.
Instances of sexual exploration are often spontaneous and are experienced as emotionally positive and sometimes “silly”. These behaviors tend to be linked to feelings of connection and attachment and they lack the erotic quality found in adult sexual behavior.
