In addition to finances, women considering staying at home with their children should also gauge their partner's support, as well as how it will affect their emotional/psychological happiness:

• Finances
  To consider how much money your family would lose by your staying at home, first subtract from your income all the expenses related to your working. These expenses include taxes, childcare, transportation, clothing, dry cleaning, lunches out, etc. What's left is the amount of money your household truly loses by your staying at home. Then see if you can compensate for the difference by either cutting back on extras (vacationing in Florida instead of France might be acceptable, but not having enough money for groceries certainly isn't) or finding out if your partner can make up all or most of the difference in income. Some women -- and all single parents -- will find that their working is a financial necessity. But many women will be surprised to find that when all the expenses are figured in, the decision to have one parent stay at home is not as financially frightening as they'd thought.
  
  
• Partner Support
  This is a couples decision, and you and your partner need to be in sync about whatever you decide. For the most part, says Gochnauer, men aren't thinking in terms of touchy-feely issues such as your desire to be close to the children. "Men want to know the bottom line: how you're going to eat," she says. If a woman intent on staying home approaches her husband with everything lined out financially, chances are he'll support her decision to stay home.
  
  
• Emotional Health and Happiness
  While mothers who work full-time outside the home feel frustrated and guilty about the lack of time they have with their children, stay-at-home mothers feel plenty of frustration, too. The most common complaints of stay-at-home moms have to do with loneliness and sense of self. The isolation of being at home with small children can be quite a shock, especially for women who'd had full-time careers beforehand. And the loss of a title and job affiliation can mean a crisis of self-identity.
  
  Combat loneliness by joining local parenting support groups such as Mothers of Preschoolers or Mothers & More. Work with your partner's schedule to find at least one time a week where you can get out of the house on your own to be with other adults -- in a book club, adult education course, exercise class, etc. And definitely keep your work skills fresh for the day when you may want to return to your career. "Go out to lunch every few months with your old colleagues, take an occasional course, keep in touch with your old business associates and contacts," advises Gochnauer.
