Mam my child born on 16sep19,he's premature,but now his weight is4.5,i want to ask he look at me but didn't give any response is it ok??

It's absolutely fine.. children begin to recognize their parents and others from 3 months onwards. For some it can be early and for some late. Each child has its own progress. Do not compare and do not be impatient. Enjoy this phase 😊

That's normal.. nothing to worry..he will smile after a month or so...
