P.G.
Perhaps the base or whatever she is connected to has some programs for helping families and kids whose parents are deployed. If this is new behavior, then it may be connected to missing dad. If it's not new behavior but is just harder to handle since dad is away, perhaps talking to the teacher/pediatrician to find out if its ADD type stuff so it can be dealt with. She doesn't have to do it alone, but she needs to ask the right people to help.
