How do I get my seven year old not to miss her mom so much?

It is normal for her to miss her Mom.Just keep loving her and be available to listen :)

If it becomes a big problem maybe she could benefit from talking to a Counselor or Psychologist whose only concern would be her.

Dont talk bad about her that u need to let ur daughter see on her own, maybe u could encourage her to call, it may not be the answers ur daughter is looking for but at least she can make those decisions for herself. Regardless she is her mother and she may have hated her but I think that as parents we love our children uncondtionally and i think children do the same with their parents. Just be there for her no matter what. And remember u as an adult may dislike their mother for things she has done but remember kids dont see what went on between the 2 of u. All she knows is thats her Mommy, just be there for her no matter what.

ask her if she wants to talk to her mom. If she doesn't want to and is really mad at her, have your daughter write a letter to her mother telling her why she is so upset at her. Let her know that she doesn't have to give it to her mom and that you will not read it. Give her an envelope to put it in. You could also get her a journal.

I think that the child should be able to see her mother if that is possible. When you say that she misses her even though she hates her...do you mean that her mother hates the child???

Let the kid see their mom even if it is a supervised visit. shes still their mother.
