I had one little one who was often inconsolable. She just wouldn't cuddle or calm at all for me. It was really tough, but we seemed to be getting through it, then they went on a 2 week vacation and when she came back she was even worse than she started. I ended up having to call them to come get her 3 days in a row just after lunch because she wouldn't stop crying or let me comfort her at all. It sucked, I felt awful and so did they. We had to decide that for what ever reason, our home wasn't a good fit for her and the found other care. I heard that she did fine with her new care giver after a couple of weeks home with Mom, but we just couldn't make it work for her here.

I hope you are able to find a solution, but if it's just not working, you may have to discuss some other options.
