I decided this year that it would be nice to establish the custom of praying a whole Rosary (just 5 decades!) for each family member on his birthday. We pray each decade for a different intention as follows:
1st decade: purity of heart
2nd decade: success in all endeavors
3rd decade: discernment of a vocation
4th decade: a long and holy life
5th decade: a happy and holy death
The last birthday we celebrated was my oldest son's and when one of his siblings accidentally started to announce the third decade when we were supposed to be on the second, my son piped up, "Whoa, whoa, whoa, you skipped one!" anxious not to get jipped out of the full benefits of this budding family tradition.
Not sure how much it had to do with the second decade being for "success in all his endeavors"...
I love raising kids!
