burping is very important atleast for 10 mins after every feed, because once burped baby feels full and sleeps well. They feel gassy pain if not burped.

even if he doesn't burp ...do t forget to keep him in upright position for a while

Baby burps or not always remember to keep baby in upright position for some time... Don't put them to bed just after feeding.

Burp sound is not important. What is important is that you hold baby upright after feeding for a few minutes.
