For infants: Lay your child on their back, on your lap. Keep your child's head and upper body flat. Hold your child steady with one hand. With the other hand, gently clap on the front of the chest and just below the nipple. Clap for 1 to 3 minutes. Repeat on the other side of the chest.

For toddlers and older: Have your child lay on their back. Gently clap on the front of the chest and just below the nipple. Clap for 3 to 5 minutes. Repeat on the other side of the chest. If your child has developing breasts, put the heel of your hand under the armpit and clap with the fingers beneath the breast.
