NTA for not wanting to deal with her baby or give her a ride.

YTA for thinking someone who exclusively breastfeeds can just switch to bottles like it’s no big deal (or that having nursed for 7 years means she doesn’t have to worry about her supply..?)

YTA for criticizing her parenting. Since when can you not have alcohol around kids? Do you live on a Mormon compound?

You could have just said you’re definitely taking the train. It doesn’t actually sound like she was asking you to take care of her baby.

I would have never been able to take a trip away from my son when he was 6 months old, due to our breastfeeding relationship. I have to wonder if you have some weird chip on your shoulder about not having breastfed successfully or something. I can’t imagine why else you would have so much bitterness about her feeding her child in the healthiest way possible.
