Lots of traveling
Think about this part of the job seriously and consider if it would really make you happy, or unhappy. Some people love traveling, even for work. Alot of people who tell you they love travel rarely have done much of it.
Traveling on vacation is fun, or at least it can be, traveling for work rarely is fun. You rarely get to see the sights, you eat alone alot, you miss many events with your family and the hassles of airports etc take a toll.
I had a position in my company that required a fair amount of travel and I finally changed positions to reduce the road time. In a couple years I was in 45 differant cities and 8 differant countries. It got old.
So, make sure you like to travel, wont mind being away from your daughter and are not offended by lukeward restaurant breakfast buffets when you consider this decision.
good luck,
