Jill,
I am sorry you are in this situation. We adopted recently (4 weeks ago) and we had to wait 5 days for the papers to be signed. I told my husband that it was hard for me to bond with the baby before that time, because I had to protect my heart a little. And we didn't even have any bad signs. Do what you need to do.
It was hard for me not to bond and I did already love her before the 5 days were up, but I still had that shield up a little. Once the papers were signed, I was really ready to love her totally. This was so different from our first daughters adoption. Then we were placed with her when she was 2 days old and the papers had already been signed. I loved her immediately.
I never used a lactaid. I just bf first, then my husband supplemented with a bottle while I pumped. I was able to go ebf by around 3 weeks (it is a little bit of a leap of faith to stop supplementing).
I will also keep you in my prayers. Let us know how it all works out.
Jennifer
