3 week old doesn’t bring wind up

My little boy is 3 weeks old and after feeds he hardly brings wind up he will do a burp or 2, I wind him half way through a feed and at the end of his feed, any tips to help get his wind up I have tried the bicycle with his legs and rubbing his tummy clockwise, putting him on my shoulder, I’ve seen at my pharmacy i can get infacol or when he’s 1 month old I can get gripe water but I’m unsure if to get them or if there’s a natural way I can help him
