Long-time lurker (5+ years ) and this is the first time I've been compelled to post as I have had it with SIL.
For a bit of background, DH has one sister who is a single mother of two children,his father has been dead for over 20 years so both SIL and MIL really rely on DH. When I first met DH he was giving his mother almost a third of his salary and he wasn't living with her. He took a step back from them when we got married which I was glad of.
So two years ago SIL was diagnosed with early-stage breast cancer she needed surgery and a course of chemo afterwards. Obviously this was terrible and DH and I tried to be supportive as possible. When SIL had surgery we had her children for two weeks while she recovered and even after that we often had them at weekends/brought them on holidays with us to give her a break.
When SIL started having treament she said she has no childcare even though MIL normally looks after the kids mid-week but she was suddenly occupied. So we agreed that our nanny would collect the kids and feed them do homework etc and we dropped them home later. I also accompanied SIL to treatment several times taking time off work to do so.
The problem is over a year ago SIL was given the all-clear. But she still continuously asks us to mind her kids overnight/for weekends. I have begun making up excuses as I feel shes using us as free childcare while she goes shopping goes out to lunch etc as she does not work.
What has prompted all this is last week SIL approached us asking if she could borrow money for Christmas as she says she cannot afford to treat her kids. I pointed out it was August and she just broke down saying it's not fair she cant give her kids what we give hours.DH and I have agreed not to give her the money as we feel she will continue to ask.
So AIBU to put a stop to supporting SIL and how would you talk her about this?
