The smaller bags hold 4oz if I remember correctly. DD usually finished the whole feed within about 15 minutes, but sometimes we did discard portions of that if she fell asleep or was not interested.
I usually took one LA with me when I went out (or two if we were going somewhere and would be away longer, if so I'd try to tuck that into a fridge if we were at someone's house, say), and brought the makings for another just in case (formula). My midwives and ped were very happy to have dd on the breastfeeding weight charts, so so long as she was 3rd or 5th percentile or so, they didn't want me to give her any more supplement, even though you could supplement as much as the baby tolerates, but I don't think it's necessary. You could get more LA systems, or wash them more often, but your guy sounds like my dd at about the same age too.
Is he getting any of your breastmilk at the breast while nursing bare?
I stopped pumping at about ten weeks. I never produced much with the pump, and it was careening me towards further sadness and frustration and sense of failure to be hooked up to that thing all the time without having anything to show for it.
As for the tubing, some women place a small bandaid there so that they can feed the tube through it whenever necessary. I'm not sure how your breast-size would impact whether or not you'd want to use tape or a bandaid or not. i found it was just one more step to do while getting ready to nurse. That's one thing you could start out doing (put the smallest bandaid you can find in the right place before you leave the house, or heck, leave it on all day) and then adjust as you get more comfortable with the LA.
