Eternal whining and crying can seem like an endless drone, enough to drive you insane. That being said, it's only been a couple of weeks. The fact that the parents offered you a little more money for the extra doting is pretty awesome in my opinion! It sounds like you've landed a golden family. Don't give up on the tyke just yet. I've had some brutal (I do mean BRUTAL) transitions, but in the end, everyone adjusted and all was fine. Sometimes they just need a little more time. I often give substantially more attention to the new ones as well. This is a luxury that every family is afforded to help the child settle in. It does take from the others to a degree, but it's temporary and every parent in my daycare knows the drill. During that time I look for the special thing that will bond the new child to me, whether it's raspberries on the belly button, sharing a snack or humming in his ear as I cuddle him. Every kid is different but on that same token, every kid has at least one thing that really blows his hair back and bonds him to you.

Hang in there
