While breastfeeding is a natural act, it is also a learned behaviour. An extensive body of research has demonstrated that mothers and other caregivers require active support for establishing and sustaining appropriate breastfeeding practices. WHO and UNICEF launched the Baby-Friendly Hospital Initiative (BFHI) in 1992, to strengthen maternity practices to support breastfeeding. The BFHI contributes to improving the establishment of exclusive breastfeeding worldwide and, coupled with support throughout the health system, can help mothers sustain exclusive breastfeeding.
Although some prescription and OTC medications are safe to take during pregnancy , a pregnant woman should tell her doctor about all prescription medications, OTC cold and pain medicines, and herbal or dietary supplements she is taking or planning to take. This will allow her doctor to weigh the risks and benefits of a medication during pregnancy. In some cases, the doctor may recommend the continued use of specific medications, even though they could have some impact on the fetus. Suddenly stopping the use of a medication may be more risky for both the mother and baby than continuing to use the medication while under a doctor's care (Pregnancy: Medications and Pregnancy, 2014) . This could also include medications to treat substance use disorders—something that is discussed in further detail in the " Sex and Gender Differences in Substance Use Disorder Treatment " section.
