Night waking, breastfeeding and parent–offspring conflict
نویسنده
چکیده
Disrupted sleep is probably the most common complaint of parents with a new baby. Night waking increases in the second half of the first year of infant life and is more pronounced for breastfed infants. Sleep-related phenotypes of infants with Prader-Willi and Angelman syndromes suggest that imprinted genes of paternal origin promote greater wakefulness whereas imprinted genes of maternal origin favor more consolidated sleep. All these observations are consistent with a hypothesis that waking at night to suckle is an adaptation of infants to extend their mothers’ lactational amenorrhea, thus delaying the birth of a younger sib and enhancing infant survival.

متن کاملThe Relationship between Frequency of Breastfeeding and Sexual Distress in Postpartum Women
Background & aim: Due to frequent waking at night for breastfeeding, nursing mothers are likely to suffer from sleep deprivation, which may lead to sexual dysfunction. To the best of our knowledge, few studies have been conducted on sexual distress in nursing mothers. Thus, we sought to examine the relationship between the frequency of breastfeeding and female sexual distress during postpartum ...
