Is it selfish of me to have a baby under these circumstances, when I work all the time?

I have been wanting to have a baby with my husband since we were first married four years ago. However I have a very demanding career. I work 60-70 hours per week and travel a few times a year. My husband does not work and he very much wants to be a stay at home parent however. He quit his job he had two years ago to follow his dream of writing and illustrating children's books which he does all at home. I am happy with and supportive of this because I make enough money for both of us. I love what I do and it doesn't feel like "work" because I love it so much. I spent 7 years in school to do what I do. If I had a baby I would not be able to breastfeed due to not having time to pump and not being able to deal with leakage when I am seeing one client after another all day long. I will have to go back to work 2-3 weeks after giving birth, just enough time to heal enough that I can go back. Would it be selfish of me or unfair to the baby?
