From Catholic Exchange:

When I am able to remember these things and keep my focus, I realize that my children help me attain holiness. Perhaps, without their needs, I would be drawn towards the capital sin of sloth. Maybe, if they behaved perfectly at Mass, I would be guilty of pride. If my food was ever warm, I might fall into gluttony. The Lord knows my weaknesses. In His mercy, my kids are actually protecting me from myself!
