No, it isn’t just happening in America.
As far back as the 1970’s in the UK, following the Swanwick Conference, the Catholic Bishops of England and Wales announced that Holy Communion should not be the time for hurt and division, but that those non-receiving should be allowed, in fact encouraged, to come forward for a blessing. Since then, it is the custom to encourage them, especially at funerals and weddings.
But this is referring to blessings by clergy. EMHCs are told in trainings that they are not to give blessings, but rather use some phrase like ‘May God bless you’, or ‘May God make you happy’ if to a child. EMHCs should never actually touch a child.
