We invited over a handful of friends to a Brunch & Books playgroup where we had a potluck brunch (it's always fun to share foods) and exchanged used books that we had doubles of or maybe didn't care for or bought at a used bookstore or thrift store. Each kid brought 5 books and we let them pick through the books on their own. Isabel thought that was pretty cool because normally she has mom standing over her looking at what she is picking out & saying yes or no. And then of course the kids got to plays lots. So, it was a fun way to recycle books, socialize, & eat the "most important meal of the day".
