I think you may try to use some breastfeed scarf to cover yourselves and feed your baby in public area like in the restaurant.
I have 2 children. I feed my older baby for over 3 years. Now I am feeding my second baby.
I 've 2 scarf one is boungt from 荷花 , and the other one is baby sling.
Both can feed in some restaurant.
They also can drink mama's milk very stable.
You know not everyone understand that These is the best food for our baby.
Do you agree?
