maybe if we knew what kind of stuff she liked we could help a little better, and your right its not easy to come by someone you can trust with your kids and that your kids love also, you really were blessed by her =]. is she into clothes movies books house decorations? maybe yall could throw her a little good bye party like a cookout with her favorite food, nothings better than home cooked meals ya know, does she have a boyfriend or husband? you could maybe send them on a date night with dinner and a movies and throw in some chocolate or flowers for just her... thats about all ive got but good luck
