I am really really upset and I could not hide it from ds. My parents have now got a new grandchild and all of a sudden they don't have any time for ds, who was the first grandchild and they used to love so much. Mum keeps on extending her stay with my sister and won't tell me when she is going home, and yesterday she rang me and cancelled all the dates in June and July when they had both promised to visit my ds at our house and for ds to go and stay with them. They said that I can get a babysitter and did not understand when I said that of course I could afford a babysitter or cancel what I was supposed to be doing, but what I had wanted was for my ds to spend time with his grandparents again. My married sister was very bitchy to me because my exp left when I was pregnant and she told me I was a failure and told me it was wrong to have a baby alone, so there is a lot of sibling rivalry on both sides lying behind this.
