It is all in our genes(?)

Maybe it's because I was trained in human genetics and spent over 10 years studying various genetic diseases, or maybe this is exactly why I was drawn into this field in the first place, but for me the inherited genetic excuse has always seemed the easy way out. No one can blame you for having or giving your children a faulty gene sequence, it is not contagious and there is nothing on earth you could do (other than not existing or not having children) to change it. Now, it is a totally different story with the non-genetic; Avoiding the exposure to different kinds of environmental factors, in ideal world of course when we know the exact effect of every single factor on human health and can avoid any unwanted effects. Some might not agree with me on that, stating they'd rather deal with something they have some control over (assuming again that they know what this something is) over the total helplessness in the light of our genes and ways of inheritance, once you have it you are married to it, in the old fashion traditional meaning of marriage, you cannot just click Delete. But the truth is that our genetics and also our environment are both contributors in shaping our life, our health and our future. Bad genetic start point can be corrected to some extent with some effort while good genetics can be totally messed up by the environment.

As a mom, though, I tend to prefer the genetic approach most of the time. Knowing that not everything that happens is my fault. Especially when it comes to the health of my children. Blaming yourself for every possible issue is always the easiest thing to do and for me it has already been set as a default from the day I became a mom, needless to say it doesn't really help. Taking the environmental approach for me it's like putting all this heavy weight on my shoulders, and then everything that goes wrong has to be related to one of the following 3 options:
1. Something that I did
2. Something that I didn't do
3. Both

And for an over protective mom like me that would just be impossible to live this way.
So we are doing the best we can in terms of the environment, hoping for the best in terms of our genetics and are mainly trying to raise happy and healthy kids and live at peace with ourselves.
