What contraceptive methods are available to and safe for breastfeeding mums?

Condoms, both female and male and intra uterine devices are safe for breastfeeding mothers. I would go with condoms as they are easily available and for its ease of use. When used correctly, they are very safe. You can also chart your ovulation and avoid the fertile days though this is risky. http://www.parents.com/parenting/relationships/postpartum-birth-control/birth-control-while-breastfeeding/
