My Sister

During my dinner with my dad and family, my step mum told me that she do not know why my sister did not want to go day care out of a sudden. So I decided to ask my sister what happened. She is told me that there are some kids at the day care that outcast her and she felt very sad. At that point I felt that if only my sister know God, Then she will know that God can help her, she can pray to God and Jesus is there to protect her. I have being wanting to bring her to church. But I do not know how to approach my dad and step mum. I will pray and by faith I will get the approval to bring my sister to Sunday school.
