My ex has turned our 2 DS (8 and 12) against both my mum and her mum so they have no grandmothers they can see. I try to take then to see my mum but they won't come because they think she is bad. My ex is paranoid in my view but what can I do? I want them to have grand parents. It causes them to also miss out on their aunts, uncles and cousins as they won't go to family occasions.
