Hi ladies! I'm going to be traveling at the end of June with DD and need to be giving her a bottle at least once a day or so as she will start daycare when we return home so she needs to get in the routine of it...but I don't want to lug my PIS around with me. Any suggestions for a small pump - manual or battery operated, that is affordable? I might even end up using it at home some too, as I'd like to start pumping the side she doesn't feed from in the mornings (to start freezer stash) without lugging out the PIS...thanks!!
