Wow, that is difficult, especially for naptime when you yourself need a break. I have had little ones that, after a good transition period, continued to just cry and cry all day. I had to let one baby girl go because she would cry all day, everyday, for so long that she would make herself vomit.

Currently, I have a 12 mos. old boy that I've had for a week, that cries at the drop of a hat. Every time I try to move to a different part of the room, have to tend to another child, go to the bathroom, etc, he screams bloody murder. It's only been a week though, so I'm sticking it out.
