there are other blessings, like the ones contained in Catholic Household Blessings and Prayers, that can be prayed by anyone who has been baptized, "in virtue of the universal priesthood, a dignity they possess because of their baptism and confirmation"

Bookmarking for this comment: "While it is true that any person can ask God to bless anyone else, and while it is true that parents should bless their children, lay people cannot bless in the manner of priests. Lay people ought not do anything which resembles blessing in the manner of the priest, such as making the sign of the Cross over people as a priest would do. That’s bad. B-A-D."
