What is the right thing to do help please?

is it right to make a child visit their biological parent even when they dont want to. if they dont want to be a part of the non custodial family. the child is 9 and definately has been influenced. but when visits happen she sometimes is fine and has fun and others acts miserable and calls home like 4 times a day always upset afterword. the biological parent has been pushed out by the other parent, has made some mistakes and should of went to court before this summer but before was trying to work with the other parent and keep things simple and out of court. is it too late expecially with the other parent who has the kid more to make a difference will they adjust what should be done. and should we force the visits. and push the family thing. what is right. thankyou
