Concerned about something 3 year old said

[missladybird]

Today dd started a new nursery. Apparently it all went well and she seemed happy when I picked her up etc.

About an hour ago she said she needed the toilet and then said "there's a plug in my bum" - I asked where she heard that from and she said "the naughty lady". I asked where the naughty lady is and she just pointed in a random direction.

I left it for a bit and then asked her about it again. I asked where the plug is and she opened her labia and pointed inside.

I'm seriously freaking out about this. What do I do?

Worrying, but my 6 year old still goes on about bums and willies and all sorts. I think it’s because it’s so innocent to them, bums are funny because they make pumps so this opens many a conversation about them! I’m guessing she’s seen a tampon at some point though.
My kids go on about pumping out rockets and all sorts.

Haven't read the entire thread yet, and this has probably been suggested, but could this have been copying something that the other child at nursery said?
