It's hard, and scary to know what to say or do when a mom is grieving. Of course we care, but we are often not sure what to say, and we certainly do not want to upset a grieving mother.
However, most likely, a mother would appreciate you saying her child's name, even if she cries. A mom wants to know her child has not been forgotten, especially on this day.
If you have a special memory of their child, ask the mom if you may share it with her. Even if her response if no, you were willing, and perhaps this will open the door for this opportunity in the future.
Learn to compassionately listen to the mom. Do not share another persons experience with a child's death. Let her know you value what and how she is feeling and you are willing to listen, even if there is silence.
Remember that even though a bereaved mothers child has died.....she is still a mom! Nothing will take this role away, not even death.
If the mom is receptive, please offer a heartfelt hug.
Please do not "bright side" her child's death. It is not a blessing, lesson, or for the best.
Recognize that Mother's Day may be difficult, and that you will support her how she wants to be supported.
Being willing to recognize a bereaved mother, is showing that you care about her and her child.
