Knee Immobilizer (again)

worked out fine last nite. She woke up once asking for it to be taken off. I took it off then put it back on after she fell asleep (within 30 minutes). She woke up this morning and asked for it to be taken off and I asked her to wait 5 minutes before taking it off. I undid two of the straps and waited. She fell asleep and that was that. So we got it in and she wasnt much disturbed.
