How about some games that they can play together? I always find that this is a great way for kids to "warm up". It always works when my DD7 has playdates with someone new & they're not sure what to do with each other. My kids love Uno, Big Trouble, Sorry, and Guess Who. Also books are great. Either ones that she can read to herself, or even better, some picture books that they can read together. Its a great way to cuddle & get to know one another. Another idea is something cooking related. A great way to spend time together. My DD loves a cupcake maker she got...its really a pain, takes about 30 minutes to make 1 cupcake, but her & her friends love it. As someone else mentioned, art kits are great too.
