My sister and I live about 120 miles from my mum, in opposite directions.
I've just seen photos on Facebook from my mums latest visit to my sisters house. Shes visited her 5 or 6 times this year and has not been to see me & my family at all this year, despite having an open invitation.
I've been to my mums house in total 4 times this year, including to drop my DS off for a weeks holiday with his cousin (sisters DD). Mum offered to do this when our DCs were little (Neice is 3 months younger than DS) when they had started school, and each summer to help with childcare. My sister has asked my mum if she'll have her DS (aged 2) next year and my mum has said she won't have enough holiday to have my DS now. when she had my DS this year I drove the 5 hour round trip to drop DS off, then met halfway the other way. My mum took my neice both ways.
AIBU to ask my mum what I've done wrong, or should I just accept that she favours my sister as she always did when we were kids??
