No judgement post

Yung little girl ko is 3 years old, may habit sya na naka dapa, yung 2 hands nya iniipit nya sa may singit tapos sabay flex ng legs. I already asked 2 pedias regarding this habit, so far wala pa daw sila na encounter. I tried telling her to stop. Pero she keeps doing it. On and off minsan, ma months na hinde nya ginagawa meron din na sunod sunod. I already checked her if may masakit or makati so far wala naman po, no uti wala din problem with urine. So i tried to do it and yun tumatama sa clit. Kinda like pinipleasure nya sarili nya. I just want her to stop baka meron kayo suggestions or same experience. Please.
