D.P.
I don't have much to add beyond what Lisa T. has already suggested, but I know that I'm always happy to cut coupons for my friends with little ones for diapers, wipes, formula, etc. so I'm sure your friends/family will gladly do the same.
Also, for grocery budget stretching you could check out
www.angelfoodministries.com
as well as
www.couponmom.com.
Coupon mom is free, easy to join and you can check the sale percentages at your local grocery store and use your coupons to get the fullest amount discount when the items are on a very good sale. They also provide the info for Rite Aid, Target and CVS (I think). It's really easy to use. Just your email info to log in.
I, too, will keep your husband, you and your little ones in my prayers. Thanks to all of you for the service to this country.
