Re: Throwing an adoption 'shower' or party?
I definitely think you should have a party, I don't think it should be called a shower simply because she has already been living with them for so long I don't think that's the right term. But it'd be a nice little get together for the family and a good memory for the parents. My son was premature, and he ended up coming home right before my baby shower (not planned that way) but I kind of remember it as celebrating him coming home, even though no one else thought of it that way or mentioned it. I agree with PPs idea about the invitations and your sister registering. Either way congratulations to the parents, that is so exciting!
