Support your child in a head-downwards position. Gravity can help dislodge the object.
Sit or kneel and support the child on your lap. If this is not possible, support your child in a forward-leaning position and give the back blows from behind.
Don't compress the soft tissues under the jaw as this will make the obstruction worse.
Give up to five sharp blows to the back with the heel of one hand in the middle of the back between the shoulder blades.
If back blows don't relieve the choking and your child is still conscious, and under one year give chest thrusts.
