Cognitive Development: School-Age
School-age children usually follow predictable patterns in how they grow and learn. This lesson will help you understand typical cognitive development, and how school-age children develop thinking skills as they mature. You will learn about developmental milestones and what to do if you are concerned about a school-age child’s cognitive development.

They know that children at these ages are figuring out what is right and wrong. Their brains are just really starting to develop.
Something in the shot 💉 or one of the boosters is going to take away their thought process.
Just my opinion.
