Babies don't always have to burp after every feeding so it could be that your baby just doesn't have any gas trapped in it's stomach to need burping.
if you feed your baby and you try to burp them and nothing happens then there's no need to worry if the baby doesn't burp.
If your baby doesn't burp in the normal way you burp the baby after a feeding you can try burping the baby while rocking back and forth in a rocking chair.
Sometimes the rocking motion will help the baby to burp.
But if not then there's really nothing you can do since it's likely your baby doesn't have gas built up that needs burped out.
There's no rule that says a baby needs to burp every time.
