My 2 year old started saying "you"/"your" to mean "I"/"my" around her second birthday, and everything I'm seeing is that this is a major sign/symptom of autism. Otherwise, though, she has no symptoms--she's very engaged, verbal and seems to understand/care about us and our feelings. We try to correct her by saying whatever she's trying to say correctly (eg. "you mean, 'show mama MY painting'") and being conscientious about switching from saying "Mama wants to play with you" to "I want to play with you" but it doesn't really seem to be sticking. Just wondering if anyone has dealt with this before and how it turned out.
