My son opened up to me that he want to take himself to school in his own by taking the public transportation. How can I encourage independence but still make sure my child is safe? Anyways he is 7 yrs old .

It depends on how far the school is from your house. If your son could reach school by riding a tricycle only, then, in my opinion, I think it is fine to give him the freedom. But if it requires a jeepney ride, 7 years old is such an early age to allow your son commute alone. Weight the pros and cons if you permit him, most especially nowadays when being a vigilant commuter is demanded.
