With twins, there are unavoidable doublings. Try to revel in all of them, especially the "Omigosh"'s you'll receive from onlookers when out and about with your precious babies. Twins are special, and as a Mommy of twins, you are, too. When you are purchasing double of the below listed items, try to look on the bright side. At least you will get through each need stage almost simultaneously. Here are the items you'll need in bulk.
1. Nourishing Food
Two mouths to feed, you can't chintz out here. Breastfeeding can work with twins, and if you can make it work, it's the healthiest choice for the babies, for you, and certainly for your wallet. If breastfeeding is not the route you decide to go, formula will do the trick just fine.
Most formula manufacturers offer special coupons and deals for parents of multiples. Get on those lists early in your pregnancy. Even if you intend to breastfeed, those companies distribute great developmental information on babies, and you never know. Best to be prepared. Likewise, once your babies are on solid foods, lots of coupons are available to mommies of twins. You'll still need to get double foodstuffs, but you can save a bit here and there.
2. Diapers & Diapering Supplies
What goes in must come out. Two bottoms, you can't chintz out here either. They need coverage. Many of the predominant diaper manufacturers put coupons in the newspaper regularly and offer coupons to moms of twins. Be forewarned. Even with coupons, the name-brand diapers are much more expensive than off- and store-brands.
You can expect each baby to soil/wet 8 to 12 diapers a day for at least the first two months. Believe it or not, you want that. It confirms your babies are getting enough nutrition. You can do the math. You will go through 960 to 1,440 diapers in your first 60 days alone. We found off-brands (or less popular brands) to be just fine. We used off-brand petroleum jelly with each and every change, and rarely had rear rashes. You'll figure out what works best for you. If friends ask what you need for the babies, you need diapers.
