Breast of Bottle?

Breast or Bottle?
  I choose to breast feed my child for the first few months of eeric's life or until he starts to get teeth.
  My reasoning for this is:
     1. It creates a closer bond between the mother and child. When the child is being breast   fed, they have a closer bond to the mother.
     2. It decreases a chance for infections. Studies show that babies how are feed from a bottle after birth have a higher infection rate than babies who breastfeed.
     3. Breastfeeding is also free unlike formula.
     4. There are also chemicals in formula that are not in breast milk that I don't understand what they mean, but in breast milk, it's all natural so I believe that it's healthier.
