I moved down south away from my parents and sister for work. So fully accept that since my sister had children, my parents can help her with childcare and they can't help us due to distance.
My sister recently went back to work after her second maternity and I knew that my mum would be helping her out a little with childcare but I had a chat with her today over Skype and turns out that my mum is looking after her baby DD2 for 3 long days a week, 7.15am - 6pm. Her DD1 is in nursery for 3 days. I was shocked at this tbh, my mum is in her 70s and my dad isn't in the best of health.
I told my sister that she was asking a lot of my mum but she maintains "oh but mum loves doing it" "she loves the children"
and says that i'm just jealous because we pay a fortune in nursery fees. Also her DD1 will be starting school in september and sis happily told me that mum will be helping with the school runs!
I really think my sis is taking advantage of my mum and want to have a chat with mum about it, i don't want my sister to start taking the piss. But not sure if its my place. AIBU?
