The "mother's kiss" technique may safely and effectively help dislodge a foreign body from a child's nose.
Canadian researchers reviewed the results of eight case series or case reports in which the mother's kiss was used in hospitals, specialists' offices, or at home (in at-home case reports, parents were doctors).
The technique was effective about 60% of the time. Smooth and irregularly shaped objects were equally likely to be expelled. No adverse events were observed.
Technique
To perform the mother's kiss, parents place a finger over the non-occluded nostril and put their mouth completely over the child's mouth.
They blow in the child's mouth until they feel resistance — and then give a short puff of air to propel the object out of the nose.
