I think nobody reads instructions! Even though I've asked people not to post queries on my first "eye contact" post, they still try to do that-- and there are so many on there already that more cannot be posted. So, let me start yet another page for these questions, and I hope the writers will find this. Here's one to begin with.
Kanza Sharjeel has left a new comment on your post "Eye Contact With Babies: What, When, Why, and How":Dear Kanza-- If your son was not only small for gestational age but born at 36 weeks, you should not expect him to be doing these things at the same times that a full-term baby would do. He does not sound as if he is very different in his development from a one-month-younger full term baby, He is not yet old enough to prefer familiar people, so although he may "know" you, it isn't yet important to him that one person rather than another cares for him.
Mu son who was sga botn at 36 weeks started his eye contact at 3.5 months . Now he is 5.5 months and no babbling as yet.. Just ooo and aaa
He has just started rollinh.
I think he doesn't recognid me. He doesn't know thst i m his mother.
He looks at me wen i cal husname
But when i cal my name in a loud voice he looks at me too. Dors this mean that he doesn't know his name?
He also doesn't etend his arms as a way of saying that he needs to b picked up
Also he has just started grabing objects and mouthing them
Mu nephew is alao autistic
Responding to the name does not usually happen until about 6 months, so he has a while to go before you would expect that. I think it's an excellent sign that he pays attention when you raise your voice-- he has learned that it's important to pay attention to the way people talk, even though he doesn't understand words yet. It's good that he is cooing, and babbling will probably start in the next month or so. I would expect him to be sitting up before he put his arms up as a signal to pick him up.
I understand why you are worried, but it seems to me that he is doing reasonably well. The best thing you can do for him is to pay attention carefully to any signals he gives you, and to try to talk to him or play with him in ways that interest him-- notice whether his eyes brighten and he seems attentive when you do something, and keep on with whatever that was for a few minutes.
Good luck to your family!
