Why is Charlotte's kid ALWAYS there??

Just watched this today for the 2nd time and I can't believe that Charlotte the moron brings her baby to almost every "girlfriend" gathering. I'm surprised she didn't bring her on the non honeymoon. I applauded Samantha when she commented on it, but that still didn't stop the moron Charlotte from bringing her baby to the all girl moving party and the all girl sleepover. I mean come on, Miranda didn't bring her little one. I get together with my girlfriends at least once every couple months and I couldn't imagine any one of us being okay with bringing our small child to our "mommy night out". Its one thing if someone doesn't have or can't afford a sitter, but obviously that is not the case with rich bitch Charlotte. Sorry, it just annoys me.
