The Guest Editors have invited authors who are well published on the current research for breastfeeding. The issue will update practicing pediatricians and other child health professionals on the current state of knowledge and practice in breastfeeding management and support. It has been more than ten years since the last issues on breastfeeding published; because those issues were popular and widely cited, it is expected that this issue will also become a valuable resource. The articles in this issue will provide pediatricians and other child health professionals with a timely update and critical new information to advocate for breastfeeding and support the breastfeeding mother-infant dyad.
