Well, this is embarrassing. I just caught my 4 year old fiddling herself down there. It doesn't look like she's deliberately trying to find any sexual pleasure, more like she's just touching her vag like it's normal. Do kids her age do this? Should I worry?

It's normal but sometimes too she feels uncomfortable over maybe itching that's why. U must check ur little girl's vag often for her not to have any bad odour women are much concerned about their vag i suggest u put salt in warm water for her to sit in do that twice a week
