Question

My daughter has a three year old son. For many reasons the father has never been involved in his life since pregnancy and on. He did not want to and his financial support was not needed. This fact is not a problem with my daughter or us. But her son is starting to ask... "where is my daddy". He is the joy of our life and has had a very good life. Could you please give us advice as to handle this question at this present time and in the future.
We all love your "old school" advice in child rearing and refer to you often! Thank you for your help.
