The Toddler Brain Development Neurons poster can be used by group leaders to highlight the emerging development of toddlers. Neurons text indicate the ways parents can strengthen neural connections in their toddlers for building social relationships, language and cognitive development, and emotional development. Parents play an important role in the development of their child’s brain, strengthening the most important neural connections that will last over time. Some of the ways neurons are strengthened include – parents’ predictable responses and routines, positive attention, child-directed play, providing healthy food and exercise, and daily reading time.
