Even though I was not trying to live for the Lord at that time, I did pray for all of my kids. I basically dedicated them to God and promised him I would teach them who he was. I knew even then that they belonged to him and that he was being kind when he allowed me to be in their lives. My prayers varied a bit with each one since I was more mature each time along the way but really I kept it simple. I just opened up and said what was in my heart.
HTH
