people will tell you you are.
I will tell you the story of my eldest child.
When he was born, he didn't look at me, didn't gaze into my eyes, stiffened when I held him, didn't do the whole looking deep into your eyes while you feed them thing you read so much about. In fact, he didn't seem to give a shit about me from day one. I used to sob that he didn't love me and he knew I was a bad mother. He wasn't interested in faces, actively avoided eye contact.
He was diagnosed with autism at 2 and a half.
I will also tell you the story of my second child.
He gazed into my eyes, he loved cuddles, he laughed and smiled at me. He was the reason I KNEW something was wrong with my eldest (he was born when eldest was 15 months old) when he looked into my eyes, when he rested in my arms, I KNEW that there was a problem with my eldest.
He (second child) was diagnosed with autism at 3 (he regressed)
So I would say, trust your instincts. Read up on it, be aware, hell, start working on eye contact and touching if you want. It can't hurt! but don't worry yourself about it. Don't let it take over. you have a beautiful baby who is perfect (whether he turns out to have autism or not!) enjoy him.
