I agree, I think you should have Thanksgiving. It would make them feel as if things are more "normal". My aunt is kind of in the same situation. My uncle is in Detox for a month so their kids (6 and 3) are going to be celebrating Thanksgiving without him. Its good for him though. He REALLY needs it. In the end (if he works hard and decides to stop drinking) it will be better for them, and they will get their REAL daddy back, not some drunk with no patience. So yeah, go for it!
