Thanks everyone. My original post just had a lot of background information that I didn't want people to be reading if there was no one that could help. So, without posting all of that, my question was...
I have a 4 year old with selective mutism and reactive attachment disorder. At 3 years old, she finally started talking to us at home. She still never spoke out of the house for another year after that, and now, at 4 1/2, she will talk out of the house very very rarely--when she does, it's a very high pitched squeaky voice. Her actual voice is deeper, fairly loud, and sounds like a completely normal voice. But this out-of-the-house voice is very completely opposite her normal voice, almost like she's choosing an "alternate" voice for out of the house. She will also do that same voice if she's in trouble for something. I was just wondering if that was normal for SM children who eventually choose to talk, or is this high pitched voice a symptom of something else? It seems like she's choosing it, because as I mentioned, at home, when she's completely comfortable and in a non-anxiety state, her voice is much lower and louder. But once she starts her high pitched squeaky voice, she can't stop it, no matter how hard she tries, until she's in a completely different environment... I have some experience with children who do that as a part of autism, but those children tend to have the higher voice across every environment and not just selectively.
