For all my fellow Native Americans I got a question for ya.?

Last week there was a beautiful ceremony at our local Longhouse. We were invited but didn't get the chance to go. It was a traditional ceremony for mothers who die in childbirth. So this got me thinking about ceremonies for infant death or death of a child. Do you know of any? I am making a website about infant loss and would love to include some information about my own culture in the multicultural section. But as you know this type of information can be hard to find. It is a sensitive issue in our community right now so I have to wait to ask around but in time I will take the better route and ask my elders. But for now I'm doing some research on my own. If you know of anything please let me know. Thanx a bunch.

P.S. I know some types of ceremonies can't be talked about and if this is the case could you just tell me the name of the tribe that has the ceremony or if possible the name of the ceremony.
