Yes, there are two babies, but that doesn’t mean you have to dupe your entire registry. Some things -- like a crib (for a few months, at least), changing table, onesies and play equipment, like an Exersaucer or activity mat -- can be shared. But other gear, like a car seat, bouncy seat, bath seats and, eventually, a high chair, should be bought in pairs. You’ll also want to load up on sheets, blankets, towels, diapers and burp cloths so you have enough to go around. Tip from twin moms: Splurge on two swings (hello, Craigslist!). Those moments when they’re both sleep-rocking will be amazing downtime for mama!
