I do. I periodically bless the rooms, doors and windows with holy water. When my kids were small I would bless them with it before they went out to school, or if they were sick.
We have a holy water font by the front door – do you? It is – frankly – often dry. Perhaps for the rest of Lent I will try to use it more frequently, to instill that habit, and get my husband to, too.
This is a sort of cool video on the subject, from the perspective of a husband and father.
Btw, there is a story being passed around about exorcists in Poland. As I always say, don’t fear the exorcists.
