Sorry, long.
I'm stuck in a really hard place between my sister and my mum.
I'm the youngest of two. DSis is older by a couple of years, recently had her first child, just moved house, happily married. We were very close growing up and still are, but I know she has big problems with me, always has done. I can't ever pin my finger on it, but boils down, I think, to her seeing me as the 'princess/high maintenance type'. Perhaps I am a bit, but meh, I don't involve anyone else in my desires for a nice home, nice things etc. Certainly don't inflict it on DSis. Disclaimer- they are struggling a bit financially since recent house move, we are comparatively very comfortable. I don't want to assume material jealousy is behind a lot of this, but I think it plays a part. I recently heard she has said to other family members that I clearly only married DH for money (so very far from the truth).
My DH lives/works abroad and I have 2 young school age kids. I happen to live very close to my mum, and she helps me work my job by picking the kids up from school on the days I go to the office. She also hangs out here a lot, we get on well. She takes my eldest swimming once a week as I can't get to the lesson.
DSis also gets on with Mum, and Mum does one full day a week childcare for them, plus quite a bit of evening babysitting.
On paper it's probably reasonably fair, but Mum does perhaps have a better relationship with my kids (their DD is only just 1yo still), she can do more with mine etc. I also get more of the ad hoc/emergency help, probably because we are virtually next door.
Mum is getting older and can be a bit flaky, forgetful, and frequently ignores my wishes for healthy snacks for the kids, but it's free childcare and not the end of the world IMO. DSis takes huge offense if Mum is ever even so much as late to hers, 'you'd never be late for Egdeh' etc.
DSis is getting increasingly irritated that I get more of mums time, and that Mum would seemingly gravitate to my place rather than theirs. It's coming to more and more of a head as I hear of frequent rows between them, DSis calling Mum unreliable, accusing of favouritism, lots of calling out behaviors etc.
DSis who I'm very close to then calls me, terribly upset because Mum has stood her ground - Mum says if I get more help it's largely because I'm one parent with two kids, Mum sees that I probably need a bit more support just now.
Yesterday they came to huge blows, and are now not talking.
Any advice? Is it unfair? Or is point scoring useless? I'm very conscious of how much help I have, but I never ask for it, I'm eternally grateful, and is certainly not assumed or an entitlement. The way DSis carries on is like she's entitled to mums help, even when she's rude to her. What can I do? Who needs a shake? Should I step out of the argument? I don't want to get involved but they both draw me in.
Any advice much appreciated
