Each age of child development is marked by a specific age and stage. I’ve used common ages and stages to divide the subpages here and they include infants/baby (0-12 months), Toddlers (1-3 years), preschool (3-5 years), grade school (5-12 years), and teen (12-18 years). This categorization helps parents understand some of the most common social and behavioral issues that tend to pop up at these ages. You’ll find that although the issues that arise are different based on age, you’ll rely on your foundation of basic behavioral principles to think about them (and to strategize). I’ll help you every step of the way – remember to check out the video library any time it’s referenced to bring you back to that key behavioral principle or two.
