hi, I still think it is better to let your kid latch on. as ebm cannot be outside of fridge for more than 2hr. dont worry about the nursing room normally is 1 parent allow only so no one can see .. just latch on.. fresher and you do not need to carry too many stuffs.
I also latch my boy when he was bf then. if you worry other may see bring a long towel out to cover it is okie
