Though I am struggling with my kids in many way, having used DE has nothing to do with it (unless you consider the fact that their issues probably have a genetic component, which I don't dwell on. Genetics are a crap shoot anyway.)
I wouldn't let someone's "hints" stop me from pursuing DE to build a family. Do you have any idea what kind of struggles the other parents were having?
I've been parenting DE children for 11 years. The DE aspect has never bothered me (after making that first decision to go forward), and so far it is a non-issue with my kids.
