This is human nature. We tend to naturally gravitate to that which we are most comfortable with, but I think what Jillio is saying is that in her opinion, one must step out of their comfort zone in order to ensure that their child is getting his or her needs met.
I also agree with that. If I am blessed with a deaf child, I think it would be encumbent upon me to make sure my child has role models that he or she can look up to. For a hearing child, that's not such a big deal, but for a deaf child it would be crucial to provide them with a nurturing environment that they can thrive in. If my family was Deaf of Deaf, it wouldn't be as crucial, because there would be several members of the family who were deaf, but in this family, it would be absolutely crucial for me to seek those role models outside the home since to my knowledge, there are no deaf members of my family.
