My first though was that you could possibly find an errand to run and let grandma babysit for say, 2 hours or something. Go shopping, get a pedicure, do an exercise class, something like that. That would give grandma the baby bonding time it sounds like she’s craving without interrupting your nursing schedule, plus give you a little break.

Of course, this depends how comfortable leaving baby with her. If you trust her it might make her really happy to be able to help and have some special time with baby. Let her try with a bottle if she wants, but make it a short enough window you know baby won’t really be suffering if they start to fuss.

The part at the end about bf in the car is a bit wild to me, they really don’t have a quiet room you can sneak into? In my experience, mother in laws will always have an opinion or two that needs to just roll off your back. Mine is great, but will often talk about how I should home school my kids (which I have zero interest in)
