My oldest is 2, and we say grace before meals and before bed we say 1 Angel of God, 1 Our Father, 1 Hail Mary, 1 Glory Be, and a variation on the “Now I Lay Me Down to Sleep” prayer:
“Now I lay me down to sleep,
I pray the Lord my soul to keep,
Guard me Jesus through the night,
And wake me with the morning light. Amen.”
If we vary at all from the “correct” prayers at bedtime my husband and I get chastised pretty severely.
I would like to do a family rosary sometime. I usually pray it while I drive home from work in the evenings, but occasionally I’ll do it while I’m on a longer ride with the boys. One of my moms groups also has a “children’s rosary” once a month that we enjoy getting to if we can get ready early enough in the morning.

My boys also cuddle with me while I say my morning prayers before getting out of bed.
We were in the habit of going to confession once a month but that has kind of fallen apart with our schedules lately. I would like to do that as our boys get older so they get used to going. I like it. When my oldest is a little less wild, I’d like to bring him to Adoration as well.
