If you have sole custody and the child's father cut her hair after you told him not to is there anything you can do about it?
There are sometimes issues between parents that are "dumped" on the child. Parents should always consider what affect any confrontation will have on the children. It would be wise to let go of personal resentment and move on. In other words, do not cause more stress for a child by battling over every issue. Especially those, that, over time will obviously resolve itself. Hair will grow back, broken hearts are hard (sometimes impossible) to mend.
