For my research, I have interviewed parents from France and Iceland. Mothers had FaceBook groups and ways to connect with other mothers. However, fathers had no way to navigate this big life change. Their FaceBook group either did not exist or was not utilized.
I think two separate support groups would be important. The father group could be similar to the Boot Camp for New Dads program. The initiative allows new fathers to learn from other fathers. I think they could expand their reach, and continue to meet throughout their child's life. Fathers need support beyond their child's first year of life.
Also, both mothers and fathers could use a support group with a licensed doctor or nurse. Many new parents have endless questions, but they do not have a reputable source of information. A support group with a licensed doctor or nurse would provide them with a place to ask any and all questions.
I have not finished analyzing my France and Iceland interviews, and I still need to interview my U.S. parents. I will update my contributions as I learn more.
