Participate in the First Friday and First Saturday devotions as a family, or as many people in the family as possible (maybe Dad has to work and can’t make it to Mass, etc.)
We have what we call “The Big Three” in our family, which is Mass, Rosary, and Chaplet of Divine Mercy. We try to get as many of those 3 in every day as possible.
Nine days before our birthdays, we start a novena for that person. For our kids, we usually do a novena to the Infant Jesus or to their patron (name) Saints. For us adults, we get to choose which novena we want to do We also do this for baptism anniversaries and Patron Saint Feast Days.
Every Tuesday you can pray 3 Hail Mary’s to St. Therese and ask her to send you a Tuesday Surprise. My biggest one was a 40% reduction of a hospital bill. I also got $20 in the mail and $100 off our monthly rent one Tuesday. But usually it’s something smaller like the kids behaving exceptionally well at Mass (or being able to go to Mass when it didn’t look like you’d be able to), or finding just the right birthday gift for someone, or getting a card in the mail from a friend you haven’t heard from in a while. It’s always fun to sit down at the end of the day and discuss what your Tuesday Surprise was!
I have a Spiritual Journal for each child and I write things in there such as when my 2 year old started “praying” the Rosary in the car with us, or when he took a holy card I was using as a bookmark, kissed it, and handed it back to me all of his own accord. Or when my 1 month old baby would automatically look up at the Stations of the Cross on our wall and smile every time. Just sweet little things like that. As they get older, I can record their 1st Holy Communions, etc.
Also as they get older, I want to give them a little present on the baptism anniversaries and make special cupcakes or something like that.
