Hello! I have a question about formula stages. We feed our baby, now 6 months old, Aussie Bubs Supreme A2 stage 1. It is necessary to move up to stage 2? According to the nutrition facts, stage 2 has, among other things, 0.08 mg more iron and 0.4 g more protein per serving. This means that our baby, based on her daily volume consumption, would get 4 g more protein daily. That seems significant. (We are about to start some BLW and purées, but I don’t imagine that she will be successfully eating many calories for weeks/months - in other words, her main source of nutrition will continue to be formula for quite some time.) The problem is that I bought a lot of stage 1 when it was on sale and still have about 10 weeks’ worth left 
. I would appreciate your advice! Thank you!
