I am thinking I may need to supplement as my LO is 9 months and I don't have a freezer stash anymore.

What things should I look for in formula for my LO. She doens't have any allergies or reflux issues from being breastfed but I still want the best for her.

Is organic important?
Whats the differences between normal and sensitive versions?
Pros and Cons of soy?
Generic versus brand name?
