I just joined the forum a couple hours ago and have spent that entire time reading this thread!
I'm wishing you (Dena) luck with Emma, you are truly and incredible woman. Not many people would take the steps that you have to make sure that this little Chi has a chance. I for one believe she does and is much better off for knowing you.
Forums can really bring out some crazy people, don't let it get to you, you know what you are doing is what needs to be done. God bless you and your family.
