Stongr, I agree with Azzork. Having an extra hour with your son would be really fun! But if your boss doesn't go for it, the first option makes sense, too.
I really get her point of view. Driving away without S1 would feel really weird. "Abandoning him" is a bit dramatic, because she has to know he'll be fine. She doesn't like it is really the bottom line here. I don't think I would feel much sympathy, were it me, but I really do understand her statement.
I just got through telling H today (WW3) that he should have thought of a lot of things before he decided to blow up our family. He was trying to guilt me into something, and I was not so politely declining. I imagine you probably feel similarly on this.
It's your day with your son. If you can work out a way that makes you both happy, that would be best. Don't give in to help her with her unhappiness of the situation. She'd best get used to it if you're unable to maneuver your hours. Going to another daycare is not a good idea.
