Long-time lurker, but first time poster.
I'm just looking for some advice from mumsnetters as this situation is causing problems for my family. :(
When SIL had her first baby, she was the classic highly anxious first-time mum and unfortunately she came up with some bizarre rules that alienated most people in the family. It ranged from reasonable requests such as no one was allowed to hold the baby without her permission to restricting contact with the baby if she felt we weren't good enough (aka entertaining) company for her child.
Whilst my parents were very sympathetic to begin with and really complaint with her many rules, they soon grew tired of it. She would for example only allow my parents to see the baby once a week, but would expect them to babysit at short notice. When she once needed someone to help and my parents had an urgent family matter to attend to she threw a fit and accused them of not caring enough. My sibling tried to reason with her, but she has tendency to start fights over small things - such as the baby returning with some food stains one her onesie - so he has now given up trying to reason with her.
Over the years, this truly took a turn for the worse as she would expect free and regular childcare from my parents so she could continue to work part-time. However, despite my parents being elderly and doing her a favour - she would give them a list of instructions and would scream at them if they were unable to meet every single requirement on that list. She would for example expect them to take her children out on days out but she would not contribute anything towards the cost. She would regularly remind my parents that they were fortunate to spend time with her children.
After Covid, I had two children in a short span and we now also rely on our parents to help with childcare and support. This has of course caused a huge issue with SIL because my parents are now not able to help her out as much. Furthermore, they find helping me out much easier than her because they do not feel criticised and anxious all the time.
Unfortunately, SIL has now decided that my parents are favouring my children and she has sent some vile and abusive texts.
We do not want to upset my brother, but we are not sure how to handle this situation amicably. They are still looking after her children on 2 days she requested, but they can no longer help her out as much. I also feel they are reluctant to take her children as what should be a nice day is often ruined by SIL at the end of the day. :(
