How much to burp a baby with reflux

Burping a baby with reflux is like a box of chocolates...well, you probably know the rest...

Even if you're scared at what might come out with each burp, I've read, and experienced, that burping is important in managing your feedings, just not too little or too much. 

In an article from the Seattle Children's Hospital website, it explains burping tips as follows:

"Burping is less important than giving smaller feedings. You can burp your baby 2 or 3 times during each feeding. Do it when he pauses and looks around. Don't interrupt his feeding rhythm in order to burp him. Burp each time for less than a minute. Stop even if no burp occurs. Some babies don't need to burp."


I feel this is the most practical advice out there. What have you experienced? Is less burping equaling more success for your baby, or do frequent and longer burp opportunities help keep more air out and food in?
