Please enlighten me, this is about my 6 years old daughter.

We saw our daughter rubbing her private part with her pants on when she is about 3 or 4 years old. At first she's rubbing it with a pillow then in the edge of the bed. Then now she is 6 years old she is rubbing it with her arm. We kept telling her to stop it pero hindi sya nakikinig and I already told my husband na baka it's time to ask a professional or a pedia about it baka pala may condition sya na di namin alam. Kasi very inappropriate sa isang bata na sa murang edad nya na magkaganyan, rubbing her private part with something, diba? Before I thought it's normal lang kasi sabi may ganun talaga sa mga bata pero until now pala ginagawa pa rin niya. Gusto ko lang malinawan at sana may maka-help sa akin dito. Thank you in advance po!#Needadvice #AskingAsAMom
