You don't have to wean her if you don't want. When I traveled while breastfeeding both my boys, I pumped while away and they would pick right back up where we had left off. You will need to pump though while away. I was still feeding my youngest at about 15 months when I went away for 3 days, I pumped once and that was good. He had a lot of milk waiting for him. I generally took my pump and if I became uncomfortable I would pump or if I was still feeding them a lot I would pump. Good luck!
