Start with this article on the Keys to Brain Development. In order to learn, children need to have a balance of novelty (new experiences), the chance to explore things again and again to gain mastery (repetition) and some down time to process it al.

Other helpful overview articles are: Developmental Milestones, Understanding Your Child’s Temperament; Gender Differences: Nature then Nurture; Emotional Literacy Overview; Building Social Skills; and Building Fine Motor Skills.

Plus check out: Healthy Risk-Taking;  Benefits of Outdoor Play.

My children are all neurodiverse – autistic and/or ADHD, so I have lots of additional resources on neurodiversity, including: Autistic? ADHD? SPD? Or Just “Quirky”?; Accessing Developmental Testing; Meltdowns; Stimming;  Autism 101; the Race Car Brain (a metaphor for ADHD); Also, my Discipline Toolbox has lots of tools I’ve found work well with neurodiverse kids.
