pros and cons to talking babies

So a few months ago I posted that Josh was talking, and how cute it is. Well it is cute, except for when he learns words he shouldn't be saying. For instance, when Ashley gets upset she'll call one of her siblings, never me or Russ, "maniaces" or maniacs. Unfortunaley she learned that from the older siblings that trickled down to Ashley as well. Well I thought that was not okay. Today I caught Josh playing in my make-up and when I took it from him and said, "NO!" He looked at me and said, "maniac." I turned and started laughing, and he proceded to keep calling me a maniac. I'm working on changing this behavior, but getting a 16 month old to stop saying a bad word is kind of like teaching a dog to poo in a toilet. Now if that is possible then soon Josh will have a cleaner mouth. :)
