To Esther: I think you should take every opportunity to teach about Jesus and God in the every day things such as if he gets a cut. Care for it and put a bandaid- in a few days when you remove the bandaid talk to him about how God heals. Just short and concrete things that he can see. Some of the Heritage Builders activities are too deep for a small child let alone for a child with Pervasive Developmental Disorder. Just surround him with Christian activities like coloring pages of bible characters- be sure they are simple and not too busy. And most of all teach him to pray for something each day and Thank the Lord for something each day. Not a long prayer or a memorized prayer that will be too busy. Maybe even go around the table with your family so that he can see each person doing this. It will keep his attention better and have more meaning for him. Good Luck! God has blessed you with this special child- maybe you can share what works with others in the future!
