M.T.
The thing is, you'll get engorged at your daughters feeding time if you don't bf or pump then. You can pump more milk when she feeds after her longest sleep or a few minutes after each feeding when you've already had a letdown but if you go a few hours without nursing, your breasts will fill. I'm not sure where you are going every day that you need a bottle, but I'd suggest finding a private place to nurse, like even your car. If your baby needs a bottle of ebm because she'll be away from you, that's one thing, but a baby shouldn't be used to bottles from mom - they often "prefer" the bottle and the instant gratification it gives, as opposed to having to work for it at the breast, so she should not expect the instant gratification from you or she might start fussing at/refusing the breast. BTW, I don't mean to sound mean, but the title of your post is misleading. These are not "emergency" bottles, these are for convenience.
