BFing came really easy to me too! I felt like it was not very important to me to do it for very long before I had my baby, (my mom always made a big deal of it so I gave it a try) but here I am 8 months later and I dread the day I have to wean her! I gave formula in the first few weeks or so b/c I thought it was not a big deal and obviously my dd agreed...she would take it then. However...I stoped the formula when I got sick of making/washing bottles and now she wants nothing to do with it!! She loves her juice and will take EBM but forget getting the formula in her tummy! Sound like everyting is going great for you and your peanut so I would not worry one bit! Count your blessings...some mommy's have a terrible time!
