AITA for refusing to babysit my grandkids because I don't want to?

I am in my 60s, and I have a daughter in her late 30s who has 3 kids under the age of 8. Last year, my husband and I moved to a different state so we could be closer to our family.<br><br>My daughter thought it was a good idea, but also assumed that I would be helping her out a lot with the kids because she works from home and needs babysitting help. However, I have a part-time job that I love and I didn't want to give it up. Also, my husband and I had plans to travel in our trailer once we retired.<br><br>She was unhappy with our decision and thought we were being selfish. And we had an argument.<br><br>Fast forward a few months, we are currently at the same house as my daughter and son-in-law are going out of town for the weekend, and my daughter asked me if I could watch the kids while they are away.<br><br>I said no, and she got upset at me.<br><br>Her husband said it's understandable because they didn't give me enough notice and I already had plans.<br><br>But she thinks I am being a bad mom and I am being selfish for not babysitting my grandkids when they asked nicely.<br><br>So AITA?
