Parents, take your children to Eucharistic Adoration. They will receive many graces from adoring Our Lord in the Blessed Sacrament. It doesn't have to be an entire holy hour; even fifteen minutes to spend with Him in this way teaches children about devotion to the Eucharist, sacrifice, and eternal love. Find out where there is Adoration in your area, and ask your pastor to bring it back to your parish if, sadly and all too often, the devotion is not offered. Helpful websites are http://www.adorationdirectory.com/ and http://www.therealpresence.org/chap_fr.htm.
I promise you that you will not regret introducing your children to Eucharistic Adoration—time spent simply loving God.
"How pleasing to our Lord in the Blessed Sacrament is the short quarter of an hour that we steal from our occupations, from something of no use, to come and pray to Him, to visit Him, to console Him."
—St. John Vianney
