wing1206,
I NEVER take bottles with me when going out with TIm. I always bf him directly. Wearing a nursing shirt and using a baby-sling enable me to bf outside. Actually, I can sometimes bf on the bus.
There are many nursing rooms in many shopping malls. Go to

and you can know many locations in which you can bf your bb comfortably
I alwasy go to place with nursery room, or feed baby before going out and come home for next feeding.
Did you try to let your hubby to use bottle to feed your baby? Sometime baby don't eat bottle offered by mom. But they will eat bottle when offered by dad or anyone other than mom.
