Peanuts?

Jersey, likes to ask a lot of questions, especially when I'm changing Phoenix. She will ask what's that, pointing to his -----, yeah I have trouble saying it. I do tell her the proper name for it but she can't say it so she calls it peanuts. I didn't think about it to much until this weekend when my sister in law was changing her son and Jersey said" Phoenix has those peanuts too." She is too smart sometimes.
