A new study from the University of Queensland shows that on average mothers get 5 hours less sleep per week than women without children, reports the Daily Mail.
It also found that fathers lose sleep each week, but not at the same level as mothers, only losing two hours of sleep a week.
The research also found that parents with children under the age of one were at the most risk of losing sleep, and that the hours of sleep lost increased with each subsequent child.
Mothers with one young child got 48.8 hours of sleep a week, with this decreasing to 45.8 hours after their second child and 44.5 hours after their third baby.
The research found that there was a ‘gender gap’ when it comes to sleep, with mothers always clocking less sleep than fathers.
The data also showed that women who are single mothers and have a professional qualification and job are getting even less sleep than the average.
