Trusted parenting sources, by topic
These are the vetted sources Leona draws on to answer parenting questions: the American Academy of Pediatrics, the CDC, the WHO, La Leche League, and major children's hospitals. They are organized below by topic so you can go straight to the source.
When you have a question at 2am, the answer should come from people who actually know, and you should be able to see where it came from. That is the standard Leona is built on.
