Humidity & Nesting

I've decided that this weather hates me. I have an enormous amount of energy but today it hit 90 degrees with a heat index of over 100 and the humidity is going to reach 95% tonight. We have zero air conditioning and a upstairs where all the bedrooms are and all the work that I want to do needs to be done. I got the girls room cleaned and moved around last night. Today I tried to spend most of the day downstairs washing/drying/folding clothes. I washed all of the sheets and blankets from our beds and all of the newborn and 0-3 month baby clothes. Tomorrow I need to prep the diapers some more. I moved the furniture around in our room, found a plastic 3--drawer thing to but the baby's clothes in. I have the arms reach bassinet next to our bed and moved our hope chest(J actually did the moving) upstairs to our room so I could put all our blankets in it. Little N's closet is better organized, some of the baby's clothes will be stored in there. I still need to set up the pack n play downstairs.
The girls are in baby watch mode. Both have told me to let them know if I start to hurt because then the baby's coming. They helped me put the plastic sheet on our bed last night so I roughly explained to them about my "water" breaking and what that meant. M wants to help cut the cord. L wants to hold the baby only if it is a girl, not a boy. One brother is enough for her, I guess. M has a bunch of supplies set aside in her closet just in case the midwives can't make it, including a basket and a blanket. They have asked me if the baby comes out with clothes on or not.
They have both seen me wash baby clothes and probably know by know what we think we are having.. I try and play it off as nothing. Please don't call my house asking them what baby clothes I am washing.
Here are the stats. With N I would have already had him. L I had at 37 weeks 5 days. Which is in a week and a day. M had a couple days after her due date. Which would be in 3 weeks and 4 days.
But back to the weather. I told J he needs to find me a window air conditioning unit. I hope he does. This weather is suppose to stay in the 90's all this week. Yucky. I just hope the humidity goes down.
