A.C.
I don't think she is developing autism but I would address it with her pediatrician. It sounds like there could be some developmental issues with her but not necessarily. My nephew is 13 years old was behind on developing as a baby. He was behind because he stayed sick and in the hospital all the time. His pediatricians told my sister that he would catch up as he got older and healthier. He did catch up somewhat but never talked a whole lot. Finally when he was 4 years old she talked to his pediatrician about him not talking because she was very concerned. She found out that he couldn't hear well enough to make words out. She took him to an ent specialist and found that he had chronic fluid that would pool behind his ears that would dull his hearing sense. They put tubes in his ears and he began to hear very well and began to talk. He never developed ear infections from the fluid and because he was behind from being sick all the time they didn't catch it. Have you had her hearing tested? I would start there to see if that uncovers some type of problem. It could be that she just needs a little speech therapy to resolve the problem but I wouldn't worry about autism.
