As for me, I chose a nice private school in our location where my kids can excel to the best of their abilities and capabilities. As early as 3 years old, my kids go to school already. And we experienced the so-called separation anxiety but we overcome it as the school makes way for my kids to feel the school their second home.
Leaving the home for school, we teach our kids to manage on their own. They became independent. They can meet different people and learn new skills and perform new tasks.
