My lovely SIL is has a long term health condition that has recently taken a turn for the worse. She and my DB have an 8 month old baby and are on their knees.
I live half an hour away and been happily looking after my DN every 1-2 weeks for 1/2 day or so while they go to doc appointments, sleep etc - if they ask, I go, absolutely no problem with this. My SIL DM lives further away but is also helping them out as much as possible.
My parents (SIL PIL) also obviously want to help too. They live nearby and pop round about once a week. However, I know from my own experience, that their help is anything but. Hinting at empty cups of tea, starting projects that don't need to be started, not offering to do any actual help with the baby, makng unhelpful comments, expecting to be fed, watered, entertained, overnight beds so they can drink etc.
Now this wasn't a problem when my baby was small - I didn't need their help and found the support I needed elsewhere. Their visits were social ones and while it was disappointing that they weren't particularly hands on, they are my parents, I love them, it was nice to spend time with them.
This is not the case now though. My DB and SIL are asking for help because they desperately need it. They can't keep accomodating my DP's visits to help because it's causing them more stress/work.
My DM is now getting offended that they are making excuses why they don't need them to pop over yet still asking me and SIL DM for help.
I love all of them and don't want my SIL and DM to end up hating each other. How can I raise this with my DM, without causing further offence, and without her thinking that my DB or SIL have asked me to say something (they haven't).
