I have been asked this a lot over the past 2 years. "How did you choose the treatment option?".
Well, is a combination of what you the mom or dad feel is right for your family and how your TTTS has developed.
Such as the laser treatment would have save both of my sons had it not been for the anterior placenta. And due to that had we chosen to terminate one son, the other more then likely would have survived. But, we did not have this information durring the pregnancy.
We can rest knowing that we gave both sons a fighting chance.
We knew we couldn't have lived with our selves if we went through with the selection and then to find out we would have had both, had we done nothing.
You basically have to search you own heart to decide. Also know, that no one can judge you. Parents, siblings, clergy, strangers, they will but shouldn't.
