join this family friendly research panel from Johnson & Johnson Company. i don't seem to have very much activity on this panel but recently i was given a product to test (and keep) and to make that deal even sweeter they also threw in $10 for my participation!
i especially think households with infants would get many opportunities to test their products. sign up is simple and then you can just wait for emails!
