<human>: My MIL is a teacher, and a few months ago she pointed out that our son (now 22 mo) sits with his legs [in a W position] We looked it up online and saw it's bad for hips and knees, so we correct him when we see it, but it's still his go-to position. Now apparently it's a possible sign of ASD?

She also pointed out a few other red flags: occasionally runs on tip toe (we correct this, too), sometimes ignores us if he's playing, likes light switches, likes wheels, doesn't like tags in his shirt (who does?)...

I guess I'm feeling overwhelmed because I thought all these behaviors were normal for little boys, and now suddenly every little thing means there's something wrong. One thing that used to concern me was that he'd bang his head on the floor when he got overtired and upset, but that's rare now (a couple times a month). He makes plenty of eye contact, is very verbal and likes to show us things and ask questions, is somewhat physical and likes to hold hands when walking or cuddle when tired or upset. 

I thought we were taking a good stance by keeping an eye out for symptoms but not worrying about every little thing, but WHEELS? C'mon, he's a little boy. He loves trucks and tractors and trains and bicycles. And I'm supposed to take him to his 2 year checkup and tell the doctor that I'm concerned he likes to flip light switches? I guess I feel like things have swung hard from not recognizing ASD at all to seeing it everywhere.

Give me a shortened version of the text
<bot>: So to come full circle to the subject line (sorry for the rant) - did anyone else struggle with getting their kid to sit on their heels or criss-cross? Any tips?
