Treating a choking infant

Paediatric First Aid current accepted best practices with
regard to administering back blows to a choking infant:

It is now accepted as best practice that the first aider should be in a seated or kneeling position and the infant placed face down along the thigh.

New text (Page 25) in the handbook PROSEC issued (for anyone who attended any of our Paediatric First Aid Courses) :

Place the infant face down along the thigh, with the infant’s head at the lowest point. Support the infant’s head by making a cradle with your fingers and thumb of one hand supporting the infant’s lower jaw.
