(OPRAH.com) -- The McDermotts are trying to insulate their family from an uncertain economy as much as possible -- the only difference between them and most of us is in a few months their family will nearly double in size.
Stacia and Dave McDermott are looking for ways to save money as they expect twin sons to join their daughter.
"We have an almost two-year-old daughter and we are currently almost 20 weeks pregnant with twin boys -- pretty crazy," Stacia says.
Having three children under the age of 3 in daycare doesn't make financial sense to the McDermotts, who already try to live on a lean budget.
That means Stacia is going to cut back her full-time work hours to a few evenings a week and start looking for more ways to save money around the house. Breastfeeding and making homemade baby food are two of Stacia's top money-saving priorities.
The McDermotts just refinanced their house, saving them $150 a month on mortgage payments, and they don't have cable or personal cell phones.
"In general, we just try to consume less, buy stuff that is used and share with people," Stacia says.
One used item Stacia will be putting to use is a refurbished double breast pump, a hand-me-down from a friend. Most of the maternity clothes she wears are part of a collection shared between her friends too.

Join a babysitting co-op
Babysitters typically charge $10 or more an hour, making it tough to justify a date night when you're pinching pennies, but babysitting co-ops are free.
"You use [the co-op] as much as you want or as little as you want, but I would say you'll save easily $100 a month," says Gary Meyer, author of "Smart Mom's Baby-Sitting Co-op."
According to Gary, babysitting co-ops are usually an organized group of women from the same neighborhood, church or circle of friends who take turns watching each other's children free of charge. Oprah.com: 9 sitcom kids we'd love to babysit
Here are some tips from Gary on starting a babysitting co-op:
• Start small. You can start a co-op with just two or three friends or neighbors who live within a driving distance of 15 minutes or less, then later grow to a group of 10 to 20.
• Be selective. Try to find women who have a similar parenting style as you, and make sure their homes are safe and clean.
• Use the point system. Most co-ops work because they run on a point system. Every time you sit for someone, you earn points. When someone sits for you, you lose points.
• Set day and night rules. If you request a sitter during daytime hours, you should drop your children off at the sitter's house. If you request a sitter in the evening, you should expect the sitter to come to your house so your kids can be put to sleep in their own beds. You will be charged more points for an evening sitter.
• It isn't daycare. Most babysitting sessions last just two to five hours, long enough to run errands, meet up with friends or go on a date.
• Learn more. If you are interested in starting a co-op, you can download a free startup kit from Gary's Web site, BabysittingCoop.com.
Focus on your food bill
Many of us already take brown-bag lunches to work, but Jeff Yeager, author of "The Ultimate Cheapskate's Road Map to True Riches," says you might want to rethink the ingredients you use. Oprah.com: 8 ways to save at the supermarket
"Lunch meat is a real tip-off," Jeff says. Instead of spending $6 to $8 a pound for turkey breast from the deli, Jeff says you should pick up a whole turkey breast from the meat case.
"I just bought a whole turkey breast for 99 cents a pound, and I'm going to roast it and slice it into lunch meat the good, old-fashioned way. It's cheaper and tastes better too," he says.
Jeff offers a few more tips that will help lower your food bill:
• Check the international food aisle for bargains. "Many staples, like rice and beans, are cheaper in that aisle than they are two aisles over, and that is because it is an off brand," he says. Items like canned tuna are often a bargain in the international aisle, and condiments like hot sauce can be more than a dollar cheaper than popular brands.
• Invest in a slow cooker. "A slow cooker is a great way to take inexpensive ingredients, like cuts of meat that could be tough, and make it taste great," Jeff says. You can put the ingredients in a slow cooker in the morning, and by the time you come home from work, dinner is ready. You can use one every day for 8 hours for just 25 cents a month.
• Always ask for a rain check. If a sale item you want is out of stock, Jeff says you should always ask for a rain check and make a point to get the product at the sale price when it is back on the shelf.
• Reuse stale bread. "It sounds quirky, but my great grandmother was big on stale bread," Jeff says. You can use stale bread to make bread crumbs, bread salads, French toast, croutons, bread pudding and more.
Rethink your laundry
Most American families of four spend nearly $4,000 per year on their wardrobe, and while some families can certainly cut back on their clothing budget, Jeff says you can also save a lot of money by changing the way you launder your clothes. Oprah.com: How to make your favorite clothes last
• Get a clothesline. Dryers cost a lot to run, but a basic clothesline and some clothing pins are quite inexpensive, Jeff says. You'll not only save money on your gas or electric bill by using a clothesline, but you'll also prevent your clothes from shrinking and keep them looking and smelling fresh.
• Only wash when necessary. Some clothes, like jeans or sweaters worn over long-sleeved shirts, don't have to be washed after each wear, Jeff says.
• Use cold water. Jeff says cold water not only costs less to use, but it's also gentler on most fabrics.
• Zip it up. If you don't zip up jeans and jackets before you wash and dry them, Jeff says you can cause costly snags and tears to your clothes.
Consider renting out a room
Ryan Cowmeadow, with the National Shared Housing Resource Center (NSHRC), says the home share program he coordinates in Michigan has had more than 500 inquires in the past nine months.
"[Home sharing] has become a viable option for senior homeowners who are looking to increase their household incomes, off-set utility costs [and] supplement retirement income, which may have been decreased due to the slump in the economy," Ryan says. "This program is also a great option for persons who have been affected by the economic downturn who need affordable housing options."
Before you open a room in your home to a renter, here are some things to keep in mind from the NSHRC's board of directors:
• Get help from a local organization. Go to the Web site NationalSharedHousing.org and find an organization in your community that specializes in matching renters with homeowners.
• Screen renters thoroughly. If there isn't a shared housing organization in your community, you can advertise your room for rent on Craigslist, community bulletin boards and more, but you must carefully screen each candidate who contacts you.
"If you have a family member or friend who can help, it's always nice to have a second opinion during the screening and interviewing process," says Kirby Dunn of HomeShare Vermont.
• Keep landlord/tenant laws in mind. There's often no lease involved in home share agreements, and most agreements are on a month-to-month basis, but Kirby says you should be aware of landlord/tenant laws in your state.
• Know going rental prices: According to the NSHRC, you can typically charge a renters fee of about $400 to $500 per month, with utilities, laundry and kitchen privileges included, in a house share situation. You can also request chore assistance from your housemate and subtract $10 per hour off the rent. Oprah.com: Where is your money hiding?
