It may sound silly but if you’ve never had a baby before, not knowing how to burp a baby is pretty common.
One of the most common methods is when you put the baby up on your shoulder, support the bottom and the head, cup your hand, and pat. You may need a little pressure to get the bubble out.
In the second method, you put the baby on your lap facing outward. Support the head, cup your hand, and give a firm pat on the back. In a moment or two, you’ll get a good burp.
