nannynoo I will pray for you for the 5th, I am sure that all will go well but a quiet word with Him upstairs can't do no harm.
I am so pleased that you have had a wonderful 6 months with your DGS and that you took a step back from the situation when you were getting stressed about it all and worked with the SS to get your DGS to come and live with you. You are positively beaming through your words, as I am sure, he is too being with you.
Your daughter has to find her own way, work it out for herself and this will only happen with time. No amount of telling her will do any good, the penny has to drop for herself and she will start to mend then. Until then I hope she enjoys the contact she has with her son and with her darling mum.
You are doing a wonderful job. You are a fantastic mum and grandma. I bet you think all your Christmases have come at once every day when you come round in a morning and remember that your DGS is with you now. You are a lucky lady, (I don't get to see mine) but then your DGS is one very lucky little boy.
