Thank you for sharing that. May I ask if confidence is something we should teach him as we would our other child who (as far as we know) isn't on the spectrum? I certainly want him to be confident.
The thing about fears. He is always so worried about his sister touching or "messing up" his toys when he leaves a room that she is in. And when we go places (this isn't a fear, I think it's a comfort thing) he takes a little bucket full of random things with him in the car and a few stuffed toys. And every time he needs it all or he will have a small meltdown. The items have changed but mostly grown in amount. It's things like that, and I've gotten off topic, that I assume are his autistic behaviors but then I wonder if it's a mix or just him being a four year old. And I probably sound so ignorant because I'm still learning so much but I hope anyone who reads anything I say understands that.
I can only view my Aspergers behaviors from recalling situations where I feel I was odd, unreasonable, or uncomfortable. It was these memories that caused me to research my behavior and discover that I was on the Spectrum. My lack of confidence comes from being thrust into actions and activities for which I was unprepared. I was a typical ASD kid who loved to be engaged with activities that I could do on my own and required some creativity. My kindergarten report card noted that I didn't like playing with others. (what a surprise). I was never mean to anybody, and at recess I found myself enjoying the role of spectator, not player. Since childhood, I have been observing people and their nuances of behaviors. Nobody told me to do this - it was 100% natural to me, and I was also aware that I was remaining an outsider. I did best having one friend at a time with whom I could do things - go to the candy store, climb trees, and play board games and ping pong. The horrible part of this was that I didn't learn group behavior. I was happiest functioning on my own or with one other person.
My kind, intelligent parents signed me up to do things without talking to me first. Piano lessons, altar boy, minor league baseball, golf lessons, day camp, over-night camp, and Boy Scouts. I lacked the guidance that come along with all of these endeavors. I had trouble reading music and if the actions as an altar boy changed because of a special day, I would screw it up. I didn't get enough time on the baseball team to gain the proper practice I needed to do well (attention always went to the star players) and I didn't know anyone on the team, since none of them were from my school or neighborhood. I enjoyed golf, but it required that you went with my mother or father, and there were no opportunities for kids to use the golf course during the weekends. It was all putting green practice and learning how to hit a drive. Day camp was taking a bus to a regional high school, standing for roll call, playing basketball or football, then a swim in the outdoor pool. None of it was enjoyable to me. Overnight camp was a real disaster. I didn't know what state I was in, you could only get things from the store with credit (none was arranged) and money didn't work. In short, I always felt that I was thrown into situations without understanding the point behind it, nor did I have any interest in it. With Boy Scouts, I never pursued merit badges. I went to the meetings, but I never did anything. At this point in my youth, I was very depressed and felt totally incapable of achieving anything. I had convinced myself that I was a complete failure.
At home, I knew I was in a place of comfort and security. I had my own room and I could arrange it as I saw fit. It was my turf. What bothered me was my brother's inability to ask permission before taking my things, and he wouldn't return them. I was always careful and took good care of my things. My brother didn't care and he would use and abuse my stuff. This turned into a form of abuse because my parents didn't know how to fix it.
I know that I needed order and stability in my life to function. Without a responsible authority figure to talk to about my frustrations and concerns, I felt very abandoned and the world around me was chaotic. This led to me feeling as if the world as I know it was destined to crush me. I was a poor student (ASD) and I could only find peace when I had no distractions. I should have been more pro-active with life, but I had experienced too many failures to believe that I had the courage and the discipline to work toward achievement. I'm a firm believer in the value of education, but the biggest hurdle for me was confidence. I really feel as if I had been groomed to take orders and to disregard my own needs and interests. I needed academic support and parental attention.
Kids usually seek approval from their guardians. That wasn't part of my life growing up. Even if I achieved, I didn't get any recognition or attention for my efforts. I'm not whining about my own life because I have managed to understand the ingredients that created my sadness and insecurities. In one way, my difficulties have strengthened me, but it has also left me far short of my potential and still short in confidence. Nobody was aware of ASD when I was growing up, and even if it were known and understood, I still don't know how it could have been accommodated. The only way I understand my ASD today is through a lifetime of tripping over potholes and barriers that exist due to ASD. You have to get up and dust yourself off. You can't undo the past. My comments to you about confidence is to make sure your son understands that with his ASD traits, he is still valuable and can learn to manage the potholes and barriers without feeling that he is deficient. Most of us with ASD have known the feelings of "deficient". What is wrong seems to pop up more often than what is right. In my view, your son has the right to protect his toys any which way he likes. Your daughter needs to learn to respect his property. Play by the rules and avoid conflict. Mistakes happen, so make them a learning opportunity.
I feel as if my post here is a prelude to more details, but I have written enough to digest in one sitting. I hope these examples have value for you. p.s. I love my parents and my siblings. I am just different.
