There can be a number of causes of reduction in libido post partum. These include the lack of sleep due to child care, effects of hormonal contraception, and sometimes the hormonal effects of breastfeeding. The situation of always being permitted can have its effects as well.
Since arousal and sexual pleasure are a combination of physical and psychological, there is a range of approaches available to a woman looking to enhance her experience of relations. These begin with basics, like making a point of catching up on sleep beforehand, taking the time for romance, savoring other forms of touch (also throughout the day) to allow arousal to build, and slowly exploring with your husband what types of touch you do (or don't) enjoy.
Clitoral stimulation can enhance a woman's sexual response — and the husband is fully permitted to stimulate his wife manually. So too can kegel exercises, contracting the pelvic floor muscles.
Sexual distance between a couple can have a negative effect on the marriage on many levels. Therefore, if the above suggestions alone to not improve the situation, please turn for help. You can start with your physician. Discuss with him or her the possibility of trying a different method of birth control. The hormonal changes of breastfeeding can also have an impact. If the suggestions of getting more sleep and making set times for romance do not help, this may be a consideration in terms of the age until which you wish to nurse.
