awwww!! I am sending lots of thoughts and hugs
for both of you. It is so sad this had to happen when you just barely brought him home too. i am going through something similar, having to part with my baby b/c he's sick. but he's being taken care of and in good hands i'm sure.
i love the pictures btw, he looks so cute and sweet!! i can just imagine how in love you are with him. hehe.
oh yea, there's another thread about hypoglycemia, that could give you good ideas on what to do when you're able to bring him home. worth a search, there were some great info.
