Well its everyone's choice but I think either you live on West or East your up bringing will effect child's personality if you are living in east and you are not praying then what difference does it make?On the other hand side there are chances that even sometimes you don't pay attention to namaaz but living in muslim countries has an advantage that may be your child will pick up good habbits if he has good muslim company.But in Western countries you have to work hard.Anywayz at the end the result is as you sow so shall you reap.
