LukaszJagielloshe bought us (my wife and I) a home and three day after we moved in she told my wife to get out with the kids and she wants a paternity test on MY son
1. Find a local psychologyst or even a psychiatrist*? in your area that speaks Polish.
2. make an apoitment to show up with your mom.
3. than tell your mom that you are taking her out.
4. bring her to the appointment and tell her that she has a problem
5. leave her with the psychologist to work on the problem
6. come back if the problem is solved, if not get her a taxi home.
hope this helps
