They clamped the shunt today, to see how the pressure holds. It's the first step to getting the shunt out, which will then get him out of ICU, and eventually out of the hospital, and back to St Louis. They were also going to send in a PT, to try to do some work with him, this afternoon, on sitting up, and maybe (but not likely) standing. He is progressing by leaps and bounds. Thank you again for the prayers, energy and good thoughts!!!
