at 10 months, the nursing schedule you have listed sounds perfectly normal for her age. i dont think there is reason to assume she is ready to wean. at 10 months, she still needs to be on breastmilk or formula for at least 2 more months. you have to be careful not to compare how she nurses now with how she did earlier. she may be nursing for shorter times, but i am sure she is much more efficient than when she was younger.
i would say that unless you have decided you want to no longer nurse for YOUR own self, that you should still pump like normal while away, and dont expect to get what she does. its just to keep your body in its normal routine. that way, when you get back, you can still nurse. if she hasnt had a bottle, and you do plan to nurse again, dont give her a bottle. it will be much easier to give her a sippy cup. if she gets very frustrated, he could use a small cup with no lid, i have heard people sometimes do that when a baby doesnt normally use bottles. it might be a rough 2 days for your husband, so make sure he is prepared.
if you have any pumped milk, i would try to mix it with formula if its no enough, but if you dont, you really have no choice. considering your body is used to feeding her a specific amount, and that you dont normally pump, its not surprising you arent getting any. also, is it a good pump?
on the other hand, if you are done because you dont want to nurse anymore, i would say to use a bottle(not cup), and not pump, but you will feel uncomfortable. but remember, its only 2 more months, you have made it this far, so you are in the home stretch. good luck
