Questions for parents of ASD children

I have a 4 year old who was diagnosed shortly after 2. He shows a lot of the atypical behaviors of a child on the spectrum and is very much like I was from newborn to now. I’m also on the spectrum but didn’t find out until my late twenties.“R” my eldest has always had this particular issues and quirks: -aversion/fear of certain sounds -dislikes some textures on his skin and types of food in his mouth -very late talker -unsure about break in routine unless it’s thoroughly explained -stimming -hyper focused on certain things, as a baby it was anything that spinsMy youngest “L” was born 6 weeks premature and I was told by an occupational therapist that it’s very likely he could fall into the spectrum as well. However, I’ve noticed some very big differences between L and R. L is very talkative. He started by saying “ah goo” at approximately 2 months adjusted age. R never babbled until 7 months. L has learned to say Mama and use baby sign at 5 months adjusted. L has no issues with texture or movement and likes typical baby things, pretty much anything that he can put in his mouth.The only things I do see somewhat concerning is L’s startle reflex. He’s spooked easily. Someone comes at him too fast, someone sneezes too loud in a quiet room and he jumps but doesn’t always cry. He also doesn’t like people. He likes to be tickled, cuddled and played with but for only short bursts and more prefers to just do his own thing. For reference, since he was about 4 months old, R wanted nothing to do with being held. He would always push away, cry and squirm until we put him down. R also preferred to play solo.R was very active. He was a very independent baby who met all his motor skill milestones perfectly. L however, will not do anything unless he’s provoked and is pretty delayed. He’s 6 months adjusted and just today figured out how to roll back to tummy. I’ve tried numerous times to help and he get upset. Today he did it on his own. I would describe him as lazy, which is funny to say for a baby but it’s true. He just likes to chill and he’s very mild. If I put him on his tummy, practice sitting up or make him do anything he doesn’t want to he has a fit. His favorite things are eating, hanging out watching his brother tornado around the house and car rides. Physical activity is like a chore for him. R on the other hand never stopped moving.My question is, can ASD appear differently later on? As I said I see major differences between my two sons but the likelihood of him being on the spectrum is high according to research. I have no issue if my youngest is on the spectrum, I just want to know how I can help. How it can manifest differently and what I should look out for that are much less common signs. via /r/Parenting https://ift.tt/3oeTkh3
