Question about 2 year old's privates

I hope it doesn't sound inappropriate, bit something I have always wondered.

Is it normal for 2 year old's vagina to be "open". I mean I can kinda see the inside. It's been like this since I don't know when.

I am not sure if it's supposed to be closed or what. No health issues or anything. And I notice it when cleaning her bottoms.

I just wonder what's normal..
