A recent survey funded by the Australian government found that men were put off, confused, and intimidated by most parenting and childbirth information because it was targeted so clearly at women.
One suggestion that came out of the questioning: men-only childbirth classes, where they can ask questions in a embarassment-free zone. [So in Australia, discussing perineal massage in a roomful of strangers is fine, as long as they're all men?]
The Federal Minister of Children and Youth Affairs did put his finger on one thing, though [sic]: "It used to be that parenting information was in fact mothering information," he said. "I think there has been a change in our society, and fathers are taking a more active role in the parenting of their children. The information available to parents has to reflect that change."
