I think it depends on the situation and also the expectations of the parent. I'm a god parent to 4 children in total and have different relationships with each. The basics of love, care, valued and commitment are present for each but my role is different. With one child, I'm the nominated guardian in the event of the parents' death. For two of the children I'm expected to back up the faith and spiritual beliefs of the parents and for the final one, they just wanted a christening party so whilst its an honour, the parents made no secret that they have no expectations of the god parent other than the basic love my child request. I haven't seen my own god parents since I was about 5 so I'm not the biggest advocate of suggesting kids need god parents but I'm trying to do better by my own god children.
