I forgot to mention that as African-American people, my son would go up to an elderly caucasian person and call them grandma and grandpa. Can you imagine the looks of shock and dismay? Even an explanation of autism didn't alleviate the negative responses he received.

My son thought my name was "Whatcha doin?" because I would always ask him this. He went between that and "Suppie", the "twinspeak" name he and his sister called me.

For my kids, yes. Pronouns have always been confusing

My son mixes up pronouns but not in the way you are asking. If he doesn't want to be bothered with me and I am asking him a question, he will say, "Leave HIM alone!" instead of "Leave ME alone!"

It is very common for children with ASD to miss label the gender of another child or adult. I read somewhere that they commonly say yes when they me no and vice versa also. My son does this sometimes
