Hi mummies, just to check i have to burp my lo till how old?

Babies don't need to be burped when they can sit up on their own. Before that, the air bubbles are unable to rise out and get trapped in their bodies, causing them to feel uncomfortable if not burped. This is also why babies burp easily when held in an upright/seated position. http://sg.theasianparent.com/burping-your-baby/
