Dini- My husband is the same way. He likes to replace everything. Probably preventative maintenance.

His dad also used to work for Firestone, so he's kind of a tire fanatic. Good luck with your tires! And I do hope the other 2 are just fine.
Christina- Congrats on all of the movements you are feeling! I've been very surprised by how much I've felt as well with an anterior placenta. I suppose it's all about the way baby is positioned.
Tara- Thanks for telling me about the wedge pillow. I will check that out. I would definitely prefer it over a body pillow because the body pillow is so large.
Beanonorder- I am sure you look fantastic!
I did not get a chance to speak with the yoga instructor before the class started yesterday. But she did this incredible stretch that worked wonders for my back! It felt so good that I even audibly sighed relief. I couldn't help it; my back felt incredible. For some reason, yoga instructors like it when you are verbal in class anyway. My back has felt perfect ever since then. I also slept great last night.
I don't know what it is about being 21 weeks pregnant, but I want to hurry up and get on to week 22. Maybe I just want to get closer to V Day. Or I don't know. It just feels like all of the past weeks have just flown by and now this one is suddenly just dragging along.
GreyGirl- How are you doing? I'm doing pretty good.
