Insights
New mothers experience significant sleep loss, with women sleeping less than men after childbirth. Cohabiting fathers also face greater sleep reduction, indicating potential sleep disturbances during early parenthood.
Area of Science:
- Sociology
- Sleep Science
- Demography
Background:
- Parenthood is a major life event associated with sleep deprivation.
- Limited research exists on sleep changes specifically around childbirth.
- Understanding sleep patterns during this transition is crucial for parental well-being.
Purpose of the Study:
- To investigate changes in sleep duration and quality following childbirth.
- To examine gender differences in sleep patterns after becoming a parent.
- To analyze the impact of partnership status on parental sleep.
Main Methods:
- Utilized data from the UK Household Longitudinal Study (approx. 1,000 participants).
- Analyzed sleep changes within a three-year window around childbirth.
- Employed Ordinary Least Squares (OLS) and logistic regression models.
Main Results:
- Mothers experienced an average reduction of 0.7 hours (42 minutes) in sleep.
- Post-childbirth, sleep duration became similar for both mothers and fathers, unlike pre-parenthood.
- Cohabiting fathers showed a greater sleep reduction (approx. 0.5 hours/30 minutes) compared to married fathers.
Conclusions:
- Becoming a mother significantly decreases sleep hours.
- Gender sleep disparities diminish after childbirth.
- Cohabiting fathers may face heightened sleep disturbances compared to married fathers, impacting family dynamics.
Abstract:
While prior studies have examined sleep across the lifecourse, few studies have investigated sleep around the birth of a child, one of the most important events to cause sleep deprivation. This study investigates changes in sleep hours and quality, paying attention to differences by gender and partnership status. Using the UK Household Longitudinal Study, we follow approximately 1,000 participants as they transition into parenthood in a three-year window. We use OLS and logistic regression to analyze changes in sleep hours and sleep quality. Results suggest that women's sleep is reduced by an average of 0.7 hours (42 min) on becoming a mother. Whilst before parenthood women sleep more than men, after childbirth women and men sleep similar amounts. Cohabiting men experience a greater reduction in sleep by around 0.5 hours (30 min) than married men, to the level similar to women, suggesting that new cohabiting fathers may experience more sleep disturbances.

Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
