dance moms

 DD's 1st recital is coming up in June.  It's a pretty big deal, about 4 shows, tickets are bought online, ect.  The girls are kept back stage doing arts and crafts and the moms can change the girls at the intermission.  I don't know the line up but DH thinks as long as DD goes early, we should leave at the intermission.  I think it's rude and not fair to the girls who go later, however, the DD's show is at 5:30, DS usually goes to sleep by around 6:30 and all of our babysitter will be at the show.  I also expect to be standing in the aisle most of the show with him because i don't see a 1 year old sitting still for more than 2 minutes.  WWYD?  Is it really rude to leave at intermission?
