Rosy I know we are all in the same boat, but how awful of your d.i.l to stop your son bringing your dgd to see you, you are very patient, I don't know how your son's marriage can last with such a sad situation 
Rhinestone you're correct about the expected babysitting. As for mediation, I take it you are asking Celebgran, but when I went,4yrs ago, the mediator was wonderful, I still remember her name; Lynsey, I wish she had told me not to go to court though, big mistake! After my session, my D & her nasty H were invited to attend, which they didn't, after that the papers are forwarded to the courts, to begin the visitation order proceedings, you can pull out of course, but you just get swept along with the process!
So nice to hear how happy you are Smileless in your new home. Yes Xmas is a very hard time of year for us estranged mums
, as I've said before, I have to turn the radio off at times & skip the Xmas happy family ads. I know I am very lucky to have my ND & baby GD, she is an absolute delight
, I've bought her a big dolls house and all the furniture & people to go with, she is a little young for it, but I think she will love playing with it.
I know you will be thinking that my pain is less, when I am with them, it is, but as soon as they are gone
I go to bed thinking of my estD&GC and wake early hours the same, till I get up and make a cup of tea, which makes me feel better. Didn't help when I took another look at those pics my ND forwarded to me, that her friend had got off FB, seeing my darling little L all grown, with short bob hair and my little GS in his judo outfit, when I looked I thought 'that is my grandson' and the pic of my estD on Mothers day, having her head massaged by the C, she looked ill to me or very depressed
Such a worry, to wonder how my D & GD are being treated, I know my GS is OK as he is nasty's beloved Son.
Did you see the supermoon this morning? It was magnificent!
