My sister and her children live 5 minutes away and visit EVERY day, my other sister lives about half an hour away and visits at least three times a week, I phone twice a day and visit monthly, my children also visit- he wouldn't come and stay with me as he would not want to be away from the others, we really couldn't as a family do anything more. We have always been so close but this woman is causing a massive amount of upset, he would never go abroad with my mum. So no we do not ever leave him on his own for even a day - but if I phone and she is there he cuts the phone call short, she turns up and takes over if my sister is there, to be honest we feel pretty upset by the whole thing.
