WebMD - Children's Health Center has excellent coverage of health & wellness in children, including developmental, behavioral, discipline, & safety issues, developing healthy habits, and nutrition. Sections on "Childhood Symptoms," "Common Problems," and "Chronic Conditions" discuss some childhood diseases, but the content is limited. The site is recommended for its valuable and detailed content about keeping children healthy, but other sites cover childhood diseases & conditions in more detail.
WebMD - Health and Parenting contains many of the parent-relevant topics found in the newborn & baby child, & teen sections. Topics unique to parenting include, returning to work after a baby, getting children back to school, family fun, nannies, separation anxiety, talking to children about sexuality & substance abuse, limiting screen time, and traveling with children. This section is recommended for its unique topics not covered in other sections.
WebMD's "Health & Baby" sections covers many issues relevant to baby health including nutrition and feeding, development, sleeping, routine care, immunizations, and much more. There are also links to information about common problems like teething, crying, colic, jaundice, etc.
WebMD's teen health section is a limited collection of adolescent health materials on issues like disordered eating, ADHD, acne, self-injury, and more. The topics explored seem random and leave many gaps in this subject. Although the materials are credible, the collection as a whole is flawed.
Zero to Three is excellent for parents seeking articles, videos, and other resources focusing on many aspects of parenting children from newborn to three years old. The site has a wide range of useful content about child care, development, behavior & discipline, child well-being, play, and early learning. The site is highly recommended for an expanding wealth of information and resources that can be used again and again.
