, tell them you would like to participate in a diaper study. If you get voice mail, leave a message, and they will call you back! Leave your name, phone number and your child's current weight/diaper size. They are currently looking for babies wearing size 4/large diapers.
Its really easy, they send you a package of diapers, you use them, and fill out an evaluation on what you think of the diapers, what you would want to be changed etc.
