Babies crossing their legs is not a sign of precocious puberty. There is a clinical sign in children called "leg crossing syndrome," primarily occurring in either sex, where children experience pleasure through the friction of the skin between their legs. This condition is often a form of masturbation, seeking self-comfort and stimulation to achieve a sense of relief. Possible causes include increased secretions due to poor local hygiene, leading to babies rubbing against each other, thus manifesting a sense of sexual satisfaction. Additionally, parasitic infections can cause itching in the perineal area, leading to symptoms of leg crossing syndrome. If parents notice this behavior, they should guide the child gradually and persuasively without scolding, while also maintaining cleanliness in the affected area and enhancing education about sexuality. Precocious puberty is mostly characterized by the development of breasts and other secondary sexual characteristics, so there is a difference between the two conditions.
