A mother comes weekly with her 10 month old, (I know this because she's always talking loudly to the her DD about how amazed she is by her being 10 months old, I heard it when she was 9 months and I reckon we'll all know when she turns 11 months, but anyhow) bringing with her a playpen that she sets up which does nothing but creates havoc as you can barely make it around this damn thing. Its 4x5 feet. The family change room is also the disability facilities and right now is very busy as well due to renovations of the change rooms, so is only for women, so lots more traffic. The woman also has a large stroller which she straps the car seat into and brings all this into the change room. She puts the stroller in front of a set of lockers, opens up the playpen, takes her DD out of the car seat/stroller and plops her in the playpen long enough to take her swimming gear out of her bag and a blanket, picks up her DD, and heads into the change stall, all this space within a step of each other. She changes, changes her DD and comes out, plops DD back in playpen, sorts out a locker, picks up DD to put back in stroller, folds up playpen and heads out to the pool. She completely spreads out over a whole 6 foot long bench and got pissy with me today because I asked if she wouldn't mind making some room for my DD to sit on the bench. A big huff and slamming around of her stuff. I quite honestly asked nicely too. When its time to get out, she does the same routine, although the playpen is set up longer as she is showering and such in the stall. The stall is by far large enough to wheel in the stroller, but she leaves it in front of the lockers and gets pissy with anyone, even staff, when it gets moved so people can get to their lockers, rightfully. Today, there was 3 disabled people and their carers there and you couldn't get their chairs around this damn thing. I'm familiar with one of the carers as we go swimming weekly, at the same time they do, (the woman in question I see on Mondays, but she came this Friday) and she asked "who's the heck is this?" I pointed to the stall and said "she's in there. She brings it every time. A bit extreme, IMO." She agreed, we chuckled and exchanged 
faces. I moved the playpen so she could get by and put the playpen back. Aside from the irritating things she says to her DD that make me cringe, like when she starts fussing, "Oh, little dudette, chillax." [grrr], AIBU to think that she should have some common decency to see how she is inconveniencing people. How can someone be that thick to not notice? DH thinks I should complain to staff, but really, it just annoys me more than anything, but should I complain on the behalf of others in this.
