Oh, one more thing, assuming you have 2 or more of the same sex, you won't need 3x the clothes. I mean, yes, you'll probably need at least 2-3 times the amount for sleepers, onesies, socks, jackets, etc. But, they grow out of the clothes soooo quickly that you really won't need as many dress outfits. Of course with two being identical, you may want to get different colors of the same thing so you can keep track of which baby is which until you learn the subtle differences. I know some people assign certain colors to one baby - say red, yellow, green to one and blue, orange, purple to the other for instance. Other people just draw an X on the diaper of one to distinguish them apart. You may want to devise a system for the first couple weeks. Most people I know can tell the babies apart within a few weeks of birth, BUT they all only had 2 babies. I'd think it would be much easier to mix them up when there are three! (We have friends who have 4 sets of twins, one singleton, all conceived naturally.) Good luck!!
