Favorite / Must-Have Twin Items

Hi ladies...I used to frequent this board when I was pregnant and on maternity leave, but just don't have time now...   (My twins are 16-months old now.)  A coworker of mine just found out last week that she's having twins, and I wanted to give her some helpful links.  This board, of course, is included.

I remember a blog posting of "must-have items" for twins/multiples, and could have swore I had it bookmarked, but now I can't find it.  Can someone help me out please?  I'll also give her any other links you find valuable.

Thanks so much, and hope you all are well!
