You can own a sippy cup designed by Kristi and her girls, Keara and Emma! It's part of an ebay auction with proceeds benefitting the Elizabeth Glaser Pediatric AIDS Foundation. She is one of many celebrities who designed cups with their children to be auctioned off for the charity.
You can see all the cups here:

Another great thing Kristi did recently is donate for a playground for disabled children through her own charity foundation Always Dream. Here's an article for anyone interested.
