Wanting to nest but can't :/ (rant)

Kaicie
I am almost 28 weeks and I really want to get the house all cleaned up and organized for when my little man arrives. It usually takes me a couple weeks to get into the habit of putting things in the new places I have planned for them. My biggest thing is getting my room clean and the bathroom clean. I live with my brothers and my father so it's pretty hard to keep things clean. Our tub is so gross cause the boys are always so dirty and they wash the dogs in our tub as well. I want to scrub it with bleach so bad but a part of me thinks "why even try if they are gonna have it dirty again before the baby is even here"  Anyone have any tips on how I can try and get them to understand? Or at least have them try and keep things clean? My brothers smoke weed in the house with the door shut but I feel like they won't smoke anywhere else just for the baby's sake. :/ drives me crazy.
