Baby dont burp after feeding

Is it ok if newborn dont burp after feeding? We always try to burp him for few mins sometimes up to 10 mins. There are times he burp, there are times when he dont burp. When he dont burp, we would put him down sideways a little, incase he vomits, he won’t choke on it. Is it ok for baby to not burp after feeding? #firsttimemom
