My son's the first "apo" and first "pamangkin", obviously they (my family) tend to spoil him and sometimes it really gets on my nerves. is there ways on how to unspoil your child?

my son is also the first apo. from our side and from my hubby's side. and yes spoiling him its very irritating. what i did, i talked to my son. i told him that i am the boss and do not listen to others even his grandparents / aunts. and my son followed that rule. he is always asking me first evrytime they will do something that he think its not right for me. hehe
