We found a car seat. The one I thought would fit, natch (Bri.tax). It's amazing how difficult it is to find a convertible car seat that actually works in the rear facing position. We have a Pr.ius and a Mat.rix and 2 of the three car seats we tried had no hope of tightening enough!
The party was ok. My "friend" ignored both me and S other than to ask S if Baby X had gotten fat yet. Interesting way to inquire about our kid. Her husband, on the other hand, was chatty with both of us and acted like there was nothing wrong.
I'm traveling again. I've traveled every month since going back to work. This time is to sunny FL for training, so it's not so bad weather-wise. But, it sucks being away from S and Baby X for a whole week. Fingers crossed that this is my last trip for a while.
