Want to come back to one phrase:

You say "If something's wrong then it's my fault as it is in my genes."

This means you would consider yourself as responsible. You cannot be responsible for something you cannot influence. And this for sure is something you cannot influence.

If you continue this thought you would say it is your mother's fault that you have been born with the spina bifida. I am convinced you would never say it like that.

And in your case- you can see how good the outcome was.

So we will keep our fingers crossed for happy and healthy baby. Nugget/Nuggette will be more than his/her genes- that is for sure.
