S.T.
My daughter is a true "momma's child" as well, and it's something I've had to manage for a long time. I think some of them just do it for a phase and then change. We have had to force the issue a few times, giving me some nights out with the gals, and Dad became more acceptable for taking care of her. If it's often enough, at least once a month, her attitude is great about staying with Dad, but if it's been a long time, she still cries when I leave, and she's 4! You can start with 30-minute trips to the salon or grocery store if you want, and work up from there. Otherwise you're basically her slave, and that's not a good lesson for either of you. Good luck!
