Thank you all for responding. It's very helpful to have a second opinion, and I'm glad to hear all of you feel my son's development is on track. It's really hard as a first time mother to know what is normal. I'm not sure where to ask questions other than places like this. I am grateful for your responsese.
No, Celou, I'm not French. I'm glad my post helped you in some way. I was a little taken aback by your post and procrastinated for a long time on responding.
I know worrying does not help. In all honesty, though, I feel like I have a really healthy attitude when I am with my son. I can't imagine he has any idea I am worried about him. I delight with him in all of his interests, including vacuums, lights, and fans. In fact, I bought him a toy vacuum cleaner the other day. He, of course, loves it, and I love to see him so happy with his toy.
He interacts wonderfully with his father and myself, and he loves his babysitter, who comes three days a week. The day care we tried though he wasn't ready, though, so we pulled him out after three days. He is quite shy. He likes to watch other kids, and will hand them toys, but then he retreats.
He sometimes wakes up in his sleep talking about the vacuum cleaner or the fan. He has is own word for each. He points at where he knows the vacuum cleaners are kept at our apartment complex, he talks about the neighbor's ceiling fan whenever we walk by his closed door. When we go into a restaurant, he points out each and every light in the place. He is 16 months old at this point.
I'd like to not worry, but everywhere I read about Asperger's syndrome, I see my son (and myself, honestly) to some extent. I had a rather painful childhood due to low self esteem and to having no clue about how to be a kid. I guess I just want to make sure that I do whatever is best for him, yet as a first time mom I don't know what's typical and what is not, so I keep looking for other opinions.
BTW, I studied mathematics in college, and am now a computer programmer. I was a bit of a misfit until I arrived at the very intense technical university I attended where I finally felt at home. There, I was considered quite social, which was a wonderful change from feeling like an oddball. Looking back, I wouldn't be surprised to find out my father or my paternal grandmother were on the spectrum, too. Both were quiet, smart, depressed, had a dry sense of humor, and were dedicated card players. If my son is like myself, my father, or his mother, that is okay, but I want to do for him what no one did for them or me...help us thrive in this world in which we do not quite feel at home. If my son is "different" that's fine, but I want to help him avoid any depression or self esteem problems if I can. My father committed suicide 8 years ago, and his mother did not die a happy woman.
I guess I'm just desperate for someone to say "Yes, your son is likely a little different than most. But with the right support from you he will thrive. Here's what you need to do...." Or "No, you may be on the spectrum, but your son certainly is not." Or "It's too hard to tell yet. In the meantime, here are some things you can do which will help him if he is on the spectrum, and would help any typical child as well".
Look at this: "It is important to note that intense and unusual preoccupations are often observed very early in development and sometimes are the first signs of AD noted by parents. For example, an 18-month-old had an extreme preoccupation with vacuum cleaners; ... Behaviors such as lining up toys (and not then playing with them), spinning wheels, fascination with fans or lights, and opening and closing doors are common..."
