Scared for my autistic son

Mom to a 3 year old autistic boy. We’re at my sister’s for the holidays, and the gap between my son and her daughter (3.5) is so, so hard for me to deal with.Her daughter is chatty, talkative, gregarious. My son doesn’t say a word, doesn’t really enjoy being around other people, just wanders around the house sucking his thumb, occasionally looking out the windows and tapping pens or pencils against them. When he gets mad, he bangs his head against the wall. My parents bought all the kids toys. My niece shrieked with excitement at her age-appropriate toys. My parents got my son a toy for a 12-month old. He ignored it and kept wandering.My son has had ABA, OT, speech therapy for almost a year. My husband and I go to all of the parent trainings. It doesn’t seem to be working. I hear all these success stories from people in my support groups of their kids blossoming and graduating out of the spectrum in a year or so. If anything, my son actually seems more severely autistic than he did a year ago.This is breaking my heart and I don’t know what to do any more. I guess we will continue with therapy because we have no other option, but I can’t imagine a future where my son is anything approaching normal, and as he grows and the gap between him and his peers continues to widen, I just feel worse and worse.Have any other parents been in similar situations? Can you share any encouraging news? I need to hear that it gets better, I guess. Because it sucks right now. via /r/Parenting https://ift.tt/2OUMBqx
