My 6yo lost her uncle to suicide, she was very attached to him, he was the constant male in her life for the 1st 4yrs. how is this going to affect her?

Hard to know but...: My condolences. We all lose loved ones ; it affects individuals differently. You have the opportunity to help her process her feelings. See http://childrengrieve.Org/about-childhood-grief ; http://www.Aboutourkids.Org/articles/children_grief_what_they_know_how_they_feel_how_help for information ; guidance consider counseling.The homeopathic remedy ignatia can also help all ages to process grief.
