3 weeks til baby

I'm three weeks away from having my second child, my first is 22 months and I feel like I'm about to loose my mind. All I want is for my hubby to keep an eye on our little girl so I can "nest" without her making messes behind me all day. But apparently that's too hard to manage and he's got "his own stuff to do" like go to the gym, clean the garage, fix his side by side (off road vehicle), have a garage sale. Like really what does any of that have to do with the arrival of a new baby. He tells me "you can manage, I clean all the time with her running around and she's fine" you mean the hour and a half you spend alone with her everyday in which she's sleeping until thirty minutes before you have to leave for work? yea okay. I just need a little help man...there's a only so much time to get stuff done when your already working ten hour shifts it takes all I have right now not to come home and not die on the couch
