I left my little guy at about that age and was still nursing him. My sister stayed with him. He did wake up at night and cry but she got him settled down. I would suggest you bring a pump since I did get engorged while I was away, ouch! It was hard being away but we all did fine! Don't be surprised if he's a little put off when you get home since they don't know how to handle their emotions, but you'll settle right back into your routine within an hours time! Good luck!
