Would you?

Let your mother in law take the baby for a day out with her family while you stay home and sleep in? She'll be taking the baby somewhere that's about two hours away and they usually spend pretty much the entire day out to lunch, shopping, etc. I'm just super anxious and worry about her driving the baby that far and also if it'll mess up her naps.... but also maybe it'll tire her out and she'll sleep better at night and I do need a day to myself desperately to sleep and relax...

Side note: we live with my MIL. She has driven the baby places before, and watched her all day and overnight before. Just never drove her this far alone before
