Rapunzel, I did learn to talk on time and did not show the "red flags" per se. However, I did sometimes do some stuff as a kid that was not by any means typical kid behavior. Like once when I was 8, I just ran down a hall flailing my arms and making an odd vocal utterance at the top of my lungs. I also sometimes would say weird stuff like once I repeated to a teacher from what I heard my Mom say, "Have you been handling raw meat?" There was no reason to say this, then again I was only 5 years old. I could come up with other examples but these are the two that I happened to think of at the moment. Other kids didn't think I was strange just because they didn't really know any better. However, some parents (including my mother) could tell something was different about me.
