Priests who scan their flocks on Mother's Day will see lots of women smiling during the many blessings, hugs and kind words.

 But if they look closer, they will also see women who are trying not to cry. Some may be embracing their children, while struggling with memories of loss.

"We have not prepared our priests to handle the complex emotions that come with losing an unborn child," said Kara Palladino, founder of A Mom's Peace, a support network located in the Catholic Diocese of Arlington (Va.). "This is something we need to talk about. Many priests have no idea the magnitude of this loss and the challenges that come with it."

Seminaries prepare pastors to deal with many kinds of grief. Often, clergy can focus on memories of life together, even after an accident or illness that takes a child.

"A miscarriage is something different. We are dealing with the loss of something unknown. … This can lead to a silent pain that many mothers try to keep to themselves. When a woman loses an unborn child she becomes part of what we call 'the sad sisterhood,' " said Palladino. 

A Mom's Peace is rooted in Catholic teachings, but its all-volunteer team helps people of all faiths. Palladino and the group's other leaders call this a "lay apostolate" -- as opposed to a church-based ministry -- since so much of their work occurs in the secular world of hospitals, mortuaries, cemeteries and other institutions linked to death and dying.

It's impossible for clergy to avoid this issue. After all, somewhere between 10 and 20 percent of known pregnancies end in miscarriages, according to Mayo Clinic statistics. Deaths that take place 20 weeks or more after conception are less common, but affect about 1 percent of pregnancies.

Palladino walked this path after losing her seventh child, Francis, who died in utero and she has lost three additional unborn children. She was stunned by how complicated, and expensive, it was to seek dignified burials for unborn children.
