I finally got off of the waiting list and into the Babysitting Co-op. I had to use it for the first time today so I could go to the ultrasound without Anna. Craig was unable to get out of work early today so this was really the only option since the ultrasound appointment would take so long.
I was super nervous about it and didn't sleep well the night before, but Anna did a great job (so the mom reports). I dropped Anna off at the mom's house and the mom said the hardest part was keeping her boys (ages 3.5 years and 8 months) away from Anna. (Anna is pretty big into personal space—especially around strangers). Anna didn't cry or otherwise freak out.
Craig picked her up and they went out to dinner and I got home shortly after they did. Such a relief to know that Anna will be able to survive in the wild if she needs to!
