My niece is having a sleepover on Friday night for her Bday. At the Bday party they are doing glamour shots with a photographer, going to the movies and having a sleepover. The next day they are having cake and icecream and presents. My family and my sisters is very close. We live within 2 min. Of wach other. My DD's age 8 and 14 often stay the night with my niece and she is going to be 13 and often stays the night here with them. However when ever her friends are around she ignores my girls. It seems she only wants to hang out with them when her friends aren't available :( she didn't invite either one of my girls to her sleepover. This is kind of upsetting to them and made me mad. What do you think? Should my niece have invited them?
