big angry boogers

we went to a little appointment yesterday. i called the doc to see what she thought about wren's increased oxygen needs. see, we'd weaned her down to 1/8 liter, then within a few days she was needing 1/2 to sat well. (with 1/4 she just hung out in the 80's.) obviously we've got a schedule to keep, so i was a little concerned with her increased needs. and of course there's the sidepoint that it could be something serious like an infection or virus. the doc said she'd like to see her in the clinic, so... off to the hospital we go- again.
