Why would Libby Lu be inappropriate?? Libby Lu is geared for girls 6-9. If you're heading out to Frisco to discuss this situation, stop at Stonebriar mall and go check it out. If you're thinking it's more for tweens or teens-you may have been misinformed. I know that my 11 year old wouldn't be caught dead there now(because it's "too babyish") but she has been to several parties there in the past and had a blast everytime! The make-overs are completely age appropriate. They do lip gloss and eye shadow(nothing that can't be swiped off with a baby-wipe), nail polish, stick-on body gems, and fancy hair-do. A younger girly girls dream come true ; )
As far as the two parties in one day issue; since the invites have already been sent out(and rec'd) for the 1st party, I think that your friend may be dissappointed with the turn out of girls that will come to hers. Even if her daughters party is at the earlier time slot, I'm sure that they have already checked their calendars and RSVP'd to the first one. Two parties in one day makes for a long day for the children (not to mention the parents). Your friends party might be more memorable if they were done on different days.
Good Luck!
