First time fathers have always been in this situation -- the time and space of facing new responsibilities and the unease of wondering if they will measure up. Our society has many more supports in place for fathers today than ever before. Try Early Childhood Parent Education, or any parenting classes that offer support for the tasks at hand. Spend some quality time just getting to know this new person in your family. Babies are fabulous!
Our society could do so much worse than it is currently doing. Enjoy what we have.
