A research reveals men are pitching in and sharing night-time nappy changes, getting up more times than women. Market analysts Mintel said seven out of ten new fathers always or often took responsibility for the task. The initiative resulted with over 57 per cent of mommies getting seven hours of sleep a night as compared with 54 per cent of fathers. The report also stated that 59 per cent mothers changed their youngest child' nappies four to six times a day in comparison to 41 per cent of fathers.
