Visiting Estranged Mothers Grave

My teen childs bio mother died several months ago. We finally found out where the grave is located and plan to visit this weekend. We never met the bio mother nor were we told about her death until after the funeral. So this will be our first experience with the bio mother.From what we can gather our child thinks the world is a better place without the bio mother around. When told about her bio mom dying it was more of a "Oh, that happens" and there were no tears.The reason for my post is the question of: Is there anything special we should be doing to help our child while visiting the grave? We plan to purchase some flowers to plant (Marigold's I think) but are not sure what else we can do. Our kid had not seen her mom in years before the death so we are not even sure what to discuss. We are trying to get more input on what flower she would want to bring/plant and stuff but she is not being very helpful. via /r/Parenting http://ift.tt/2vnrHb3
