Mags new favorite word

Maggie has decided that everything must end with the word "boob". I am sure this is something that Emma has taught her and Maggie likes to call Emma this, and amazingly she can use it at the correct times! But this makes Emma crazy! and really isn't a very nice word for a 2 year old to be using. So we have started to try and convince Mags that it's not nice with a time out. She really doesn't care about time outs. She just sits on the couch and looks around. She did ask for her Pup Pup today and I told her "No, you don't get any comfort items on a time out." Oh ok she says and just continues to look around. Ten minutes later she asked me for something as I was walking into the garage and I said no, as the door was shutting I heard her say "BOOB" Oh man seriously. So I marched back in and she heard me coming and started to squirm. I didn't say anything and grabbed her by the arm and took into the front room sat her on the couch and said firmly "We DO NOT use that word!" She looked upset but sat there again for her 2 minute time out. I don't think those work for her? A little while later I told Emma she needed to teach her something else to call her so I heard Emma say "Maggie u can call me Captain, OK?" oh man....
