Can I leave my baby and come back to nursing?

[2beauties]

DS is almost 13 months old. He is only nursing 2 times per day, morning and night. I have not been on a date with DH since he has been born. We are wanting to do a get away weekend on Sept. 10th, but I am not really ready to wean those feedings. Can I leave him or will he just wean? Will my milk just dry up? I highly doubt I will respond to a pump. I just don't know what to do, and I am torn. I am not done nursing, but he could wean easily. He takes a straw cup all day and does great, and never goes to sleep nursing. Any advice?



THanks!
