headisspinning and life is short you cannot change the past, only look ahead to the future. TotallyADD and I raised our boys in the WT cult. They grew up and married JW women as well. The oldest one is totally out and the youngest is biding his time until he can escape with his family. You will find that children are very resilient. So give them a chance and help them find their own way.
Make your own family traditions by introducing your unique celebrations as you are comfortable with them. Keep in mind you and your family have come out of a destructive mind controlling cult that has filled your heads with so much fear and guilt that it will take time to minimize. I don't think it ever goes away. Gradually replace the negative thoughts with positive ones. Nancy drew's suggestion of celebrating your child's birthday because he is special is a good one.
The WT continually harps on birthdays as being bad because a murder ocurred during two pagan celebrations. Yet they forget that the Christian Greek Scriptures opens with the angels celebrating the birth of Jesus. (This is not surprising since the governing body has replaced Jesus with themselves, the faithful and discreet slave.)
