I’m glad to see most of the responses are helpful.
i was expecting the usual AIBU pile on around “entitlement” and how you can’t expect your mum to look after your kid as it’s her time.
but sense seems to be prevailing
i I had a similar issue with my parents over 25 years ago. Still bloody remeber it due to issue it caused. I never asked them for childcare, they lived 200 miles away. I had to go on a course with work that meant overnight stays for 4 nights/5 days . My husband was in shift work so impossible for him to look after dc for all that time and couldn’t get time off. I asked 2 months out, got a yes. Asked agian 4 weeks out at point before company committed final funding to course provider (£3000 even 25 years ago). With 2 days notice they pulled out. No explanation. Just we’ve decided it is better not to. No negotiation. I had to go into work and explain to my senior management thst I could no longer attend due to childcare committments falling through. It doesn’t take a genius to know the ramifications - I didn’t ever get to go on that course which would have enhanced my career for next 5-10 years. My flexibility and commitment levels were questioned and doubled for years to come. My promotion was held back and I was generally perceived as a “mum who worked” rather than a professional for years.
never told my parents this. Wish I had. I never ever trusted them again with childcare . Made no difference to them , probably never realised I hadn’t asked again. But at least I knew where I stood.
whilst parents pulling out of commitments for social events or to help out, pulling out or adding caveats for key career events is appalling. You’d think that you’d parents would want to support you. As poster say this isn’t about dog vs baby, this is about understanding the criticality to your future of this interview and ensuring you are set up to succeed. I’d like to think in those circumstances I’d push back on sister dog request and say “nope, I want to ensure daughter interview goes well and she’s not stressed out by doggy logistics on the day”.
as people say, the dog can be left for a few hours surely- most dogs can manage 6 or so hours - even as puppies my siblings dogs could manage 4 hours and they can do a good 6-7 now…even if there is a “hurry up I’m bursting” look on their faces when I arrive to let them out 🤷🏼♀️🤣🤣
perhaps have one more try OP, to explain this is about your future prospects and security, it is a one off, and the options she’s giving you will eat away at any time to focus and get your head into the space needed to perform well. Could you explain to your sister too, ask her what she can do to help resolve the issue ?
