My son was a tough burper too, but it really hurt his tummy! I tried multiple times to burp him throughout the feeding, and could usually get 1 or 2. I would put him on my knee and tap his back while rotating him and bouncing him... this takes practice, but helps :). I also would put his back on my tummy while he was upwards. I pump his legs up and down and this would let some gas out the "other end". Sometimes I would carry him around laying over my forearm. I also would lay him over my leg and tap his back. Good luck! Oh... mylicon helped relieve his gas too, and it's totally safe. I even asked my naturopathic dr. about it, and he agreed it's ok to use!
