Everyone knows the "over-the-shoulder" approach to burping, and that works just fine. If you want to take your infant burping technique to the next level, though, try this tip from my twin-in-law:
Sit your young infant on your knee, and support their upper chest and jaw with your hand, so that their head doesn't fall too far forward. Let their torso collapse forward a bit, bounce your knee, and pat their back with your other hand. Professional-grade burps, every time.
