Thank you all for sharing your experience.
The bariatric surgeon and nutritionist had conflicting information on the topic. My baby is 6 month old and has started to eat pureed solids which has reduce his intake of breast milk. I started to supplement with formula just incase breast feeding became an issue afterwards. However, after reading rachelzf post I feel more at ease.
My main reason for going down this path is to be an example for my little one. I want him to have a more healthy relationship with food than me. My husband and I make it a point to make all of own baby food from fresh ingredient. Which will be convenient since it looks like we will be eating a lot of the same things after post-op.
