She has never had a realtionship with them. DD is 4 and used to moan if she saw her. In all fairness, Step FIL would play with her/colour etc occasionaly but MIL would sit, moan, talk about money and drink tea. I have no idea why she bothered coming down.
When DD would ask her to play she said she couldnt cause she was drinking her tea. 
The reason she would come down was because DH would pick her up and take her home once a week, during the week. At a time that was best for her, not us, days that was best for her, not us.
If she could do a certain day, and we had plans, we was expexted to change our plans to suit her, if we didnt she would moan we was stopping her seeing DD1 and guilt trip us.
She would often cancel. Even if we had changed our plans for her. This went on for 3 years.
She would cancel due to tierdness, period pain and. nce because she was hungover. She would then moan she didnt see dd enough. She lives 20ish mins away and is early 40s. When DH couldnt pick her up anymore she StepFIL would bring her down on a weekend.
Dh had a change of hours, i was heavily pregnant/due dd2, dd1 started pre school and we couldnt do weekends anymore. So we gave her a few weeks notice to arrange transport and she ignored this and just contined to text/guilt trip..then got stepFIL involved...we told her we didnt need this with a newborn and i had PND and was told to stay away from stress....she contined and honestly didnt care.
She couldnt be bothered to arrange transport so gave us abuse. It was horrible. It was like we had to drop everything and continue planning our life around her. It got too much and we just decided NC.
Ive had no panic attacks, anxiety attacks. Its.been fab. and now this again, i feel so anxious.
Sorry about the essay.
