Good luck with this Maniac. It would be interesting to know how many were accused of harrassment but no such orders taken out, as some grandparents have been threatened with this in an attempt to alienate them.
In my case, when I got my grandson's mobile phone number after Christmas (so I could phone him in the event of him not seeing where I had parked when I was allowed to meet him from school and take him home), I shared the number with my other son, grandson's uncle - he adores his uncle. My son sent a text later that day, saying 'thinking of you - love you loads - hope to see you soon.' Ex-DIL then threatened me - 'you are giving son's number to people and police will be informed if he is texted again!' One text! I ignored it, she was probably drunk and it hasn't happened again - his daddy, uncle and aunties, and myself send texts now, which grandson is very happy about.
