Thanks all for the advice. I avoided the R talk and said to her (via email) that I thought option 1 was the most practical and that I didn't like option 3 at all. I then said that I would think about other options.
I'm thinking that when she brings it up again, I will tell her that if her mom won't help her,(it's a possibility becasue her mother can be odd. W called her once when she was 16 and asked her to come and pick her up becasue her car had broken down in the middle of nowhere. Her mother refused) I will come out and pick up the kids and take them to school/babysitters. It's kinda sucks to have to do that because it is about 30-40 minuted out of my way in the morning but it will also probably lead to me taking W to the train in the morning and picking her up at night. This will give me some talk time with W and the possibility of "do you and the kids want to go to dinner" So it might suck time wise, but I see it as a good thing for the sitch.
