The trick is to enjoy life. Don't wish away your days, waiting for better ones ahead.
I know it is hard for you young mothers to believe that almost before you can turn around the children will be gone and you will be alone with your husband. You had better be sure you are developing the kind of love and friendship that will be delightful and enduring. Let the children learn from your attitude that he is important. Encourage him. Be kind. It is a rough world, and he, like everyone else, is fighting to survive. Be cheerful. Don't be a whiner.
