Mom of 3 I really respect your views because the toughest job is even though you are not muslim but you want your children to be Muslim.It is hard but not impossible and if you are doing it and when you will be doing you will find peace for yourself too. I don’t know but some how I believe that if you are doing something right even though you didn’t do it for yourself and for the sake of your children; you will be rewarded and it sure indeed is a very good thing.
In my opinion you should tell children about religion and when they will be adults they will decide.But I think so you should keep practicing and teaching them Islam.
