Men, these days, are embracing fatherhood with the round-the-clock involvement their partners have always dreamed of -- handing night feedings, packing lunches and bandaging knees. But unlike women, many find they’re negotiating their new roles with little support or information. "Men in my generation (aged 25 - 40) have a fear of becoming dads because we have no role models," says Jon Smith, a writer. They often find themselves excluded from mothers’ support networks, and are eyed warily (警觉地) on the playground.
The challenge is particularly evident in the work-place. There, men are still expected to be breadwinners climbing the corporate ladder; traditionally-minded bosses are often unsympathetic to family needs. In Denmark most new fathers only take two weeks of paternity leave ( 父亲的陪产假) -- even though they are allowed 34 days. As much as if not more so than women, fathers struggle to be taken seriously when they request flexible arrangements.
