Florida and a baby

Well, here I am in beautiful Florida.  I am visiting my best friend, who I haven't seen in 4 or so years, and her husband and new 2 month old baby.  Her baby is absolutely adorable, I love her very much, but I can't help but think that I may be a very selfish person.  I watch my best friend feed the baby whenever she is hungry, no matter where we are, and jump up whenever the baby cries.  She is a great mother but I keep thinking that I don't know if I could make that kind of commitment.  When I am hungry I want to eat now, I don't want to wait until the baby is done eating to eat myself.  If I am watching TV and am interested in the show that is on, I don't want to have to pick up the baby and console them and miss the TV show I am watching.  Does this change if the baby is from you?
