TV - The new TV guy came last week. He took one quick glance at the screen and knew what the problem was and how to fix it. He even said that he could fix it at our house! Why weren't we referred to them at the beginning?!?!?
Heater - It wasn't the thermocouple because our heater doesn't even have one! It just needed cleaned. I guess a valve was dirty. We have heat again and it was so nice to have Luci wake up with warm hands again.
Clogged duct - It took almost 48 hours, but it is unclogged. I tried all sorts of home remedies (Cara - I tried our little secret multiple times!). Then I read on the internet about a certain position when nursing (it's a little too embarrassing to type here, but if you want to know, I can send you the link via email), and it worked within 2 minutes! I was so relieved!
