Question around Go & Grow Formula?

My son is 9 months old and I was thinking about shifting over to Go & Grow formula. I was just wondering if this formula is meant to replace his Similac alltogether or what?

Not to mention the price difference, but that isn't my motivation for varying.
Answers:    I believe Go and Grow might be for after a year old. If you do choose to switch consult with your doc. Also it does replace his similac altogether..
