I Will defiantly pray over this for your little girl and I would suggest that you and your wife keep doing the same. The fact that your not religious does not mean that you dont know that the lord exist. The fact that you are asking this even if its to cover "all the bases", means that you know there is a higher power than us all. May the lord bless your family and heal you little girl and bring you close to him, IN JESUS NAME AMEN!!!
