Diaper changing is a messy sport. I am constantly trying to prevent an impending disaster from taking place. Oftentimes, it's more convenient to change Emily on the couch or on the floor instead of the changing table. I don't always have my favorite waterproof changing pad handy.
So my mother suggested to just slide the new diaper underneath the old diaper before I change my baby. I know it sounds so simple but it has made changing diapers a relatively stress free process. The new diaper catches any spillover or mid-change pee from soiling my furniture, carpet, blanket or whatever is underneath.
This is also great for public changing tables in case you forget your changing pad. Your baby's bottom will be protected from the germ saturated surface by the new diaper underneath!
