I haven't wanted to chime in, but ilima said what I feel.
Do what is best for you. I didn't want to breast feed and the thought of nursing 24 hours a day would not have been even been in my thoughts. My kids both had solid food at 3 months and guess what? They are healthy, normal adults.
No flames, please. I knew myself and I was not willing to give up everything to nurse, most especially sleep. My DH did the middle of the night feedings, so i could get up at 5.
I know I am in the minority, but it worked for all of us, especially since my husband was a stay at home dad for the oldest one.
