We traveled when my youngest was 5 months but I found it to be completly exhusting!!!! My biggest tip is that you may need to get a mid day rest. The baby will likely sleep anywhere but YOU will be walking all day and then up a few times in the middle of the night. In our case, I didnt' realize how much the being up early to feed the baby before we left, being the last to bed becasue I had to feed the baby and then up 2X's more than the rest of the family really wore me down FAST. By the third day I was in tears ready to go home. After that, we forgot about RD, and I took a mid day nap and it made a HUGE difference.
