K.,
Our daughter wore a DOC band from ages 5 to 7 months. The first night was the hardest. I did the same, rocked and comforted her back to sleep, but I didn't take it off. She was wearing it 23 hrs a day by the third day. For the first week we took it off for 10 minutes or so every hour or two to check for pressure points. She got used to it pretty quickly, I guess we were lucky. She did, however, never sleep very good with it on. She never slept very good before, so I wasn't sure if it was directly due to the helmet. We were up 2-3 times a night. We stuck with it and wore it 23x7 and were able to get out of it a week earlier than predicted.
I hope it is going better for you now and she is getting used to it. Other options are to re-check the fitting. I asked so many questions to our clinicians. Also her temperature may be an issue. She had her helmet on during 'winter' (which isn't that cold!) but it helped to keep her cooler. That helmet can really hold the heat in. Good luck!
