Experts say placing the baby face down along the thigh offers much more support for while the parent or carer administers blows to the baby's back to tackle choking.
The change in advice, to be officially announced on March 3, comes as a survey shows one in five North East parents don't know what to do if a child is choking.

"If an infant is choking then, in the first instance, they should be laid face down along your thigh and supported by your arm, give them five back blows between the shoulder blades with your heel of your hand.
Check their mouth for any obstruction. If there is still a blockage then turn the infant onto their back and give up to five chest thrusts.
Use two fingers, push inwards and upwards against their breastbone. If the obstruction does not clear after three cycles of back blows and chest thrusts, call for an ambulance and continue until help arrives."
