My lo is 2 and she's been putting hand down her pants itching her privates. could this be a sign of infection? can it be cured with home remedies?

Possibilities : This could be from several sources, including pinworms, uti, yeast infection, nonspecific vaginitis and others. If she has a high fever or appears ill, have her seen today. Otherwise this can probably wait until your physicians office opens Monday morning. Each of these has a different treatment, so its important to get the diagnosis correct! Best of luck!
