If you are single, or married with no kids yet, then you have no excuse to skip Sunday’s Mass.
When you have a baby, or any children under 5 years old, it’s understandable, especially when mass is scheduled 2 to 3 times only on Sundays. If you live in an area where mass is scheduled every hour, go to church whenever you can.
I believe that God will understand and appreciate the care you are giving to your kids. Parenthood is just too hectic during infancy and toddlerhood.
