I'm not particularly close to my family - lots of back story but I feel resentful towards them for the way they've treated me . I'm not sure if this is clouding my judgement!
I will graciously accept if I'm being unreasonable . 
I have two sisters .
Eldest sister has a 10 year old son whom I've always purchased birthday / Christmas presents for .
I'm the middle sister and I have twins aged 5. My eldest sister has always purchased my children gifts - but it is very clear it's done out of necessity rather than want .
Youngest sister doesn't have much money and has never purchased gifts for mine - she buys for eldest sisters child though .
Eldest sister and youngest sister live close by to our parents.
I live around 3 hours away from all of them.
It was decided by my family last year that they were no longer going to purchase birthday / Christmas gifts - for adults or for children. Fair enough, however I didn't agree with the principle of not buying for children.
My children received nothing for their birthdays, not even a card . I bought my nephew a token present for around £10.
It actually transpires that my family still buy gifts for each other amongst themselves - my children are the only ones that don't get anything! From aunts or their own grandparents .
I've given my nephew his Christmas present already and I will continue to buy gifts for him .
My youngest sister has now had a baby of her own and it's coming up to her first Christmas .
I'm so torn on what to do . I'm hurt that my children are not thought of as important enough and youngest sister has always bought for her other nephew , but never mine.
However , I'd feel absolutely awful not buying a gift for the baby ! Because I know how much it hurts me 
Do I:
A) not buy for the baby in the hope my youngest sister will realise how unfairly she's been treating all her nieces / nephews
B) buy for the baby and set a precedent of gift buying where I know my children will still get nothing
C) Fuck the lot of them and don't bother any more
I don't care about stuff - I'd be happy with a bag of chocolate coins for my children - it's just the principle that they are treated like an inconvenience - the same way that I'm made to feel and it saddens me greatly
