J.K.
OK - I'm normally a lurker here but thought I would add my two cents. I'm a working mother whose job requires that she travels - often. And if I were to be completly honest, I don't feel terribly guilty about it for a couple of reasons:
#1 - Most importantly, it is a great opportunity for my husband, also a great father, to have to take sole responsiblity for my son's care. Even though my husband is an active father - he always deffers to me or 'lets me' take care of Evan if we are together. I believe that my trips have really deepened their bond and provides my husband with a great perspective on what I do on a more regular basis.
#2 - I strongly believe that a happy mom makes a happy child and working does make me happy - even if I do have to take an occasional business trip. Plus, I feel as though I'm teaching my son to admire, not fear, strong successful women
#3 - Getting away, even for work, does allow you time to yourself that you don't often get - even if it is sitting down to eat breakfast while reading the paper. I usually feel that I come back refreshed and enjoying and appreciating my child/spouse/life even more than I did before I left.
#4 - Usually when I'm away, I focus almost all of my time getting work down which then allows me time to fully enjoy my family when I return. If you are like me at all - you feel guilty that you aren't working enough at your job and guilty that you aren't spending enough time with your son. I like to use these business trips as a means to catch-up with work and ensure that when I return home, I'm able to spend time with my son.
I'm not trying to sound like a robot-mom without any feelings and I totally respect those who don't want to leave their children at a young age. I also think that the other posters have great advice to bring pictures, call often, etc. However, I think that its also important to leave without feeling (too) guilty. A business trip does not make you a bad mother. Enjoy yourself and get some sleep while you can :)
