I sympathize but would urge you to reconsider. There are activities where "properly or not at all" is a good policy, but raising children isn't one of them; had such a policy been universally applied, nobody now living would be alive. Those who were never born are just as dead as those who were born and then died, and surely your children would be much better off dealing with the imperfections that are an inevitable part of life, than not being alive at all.
