What is the difference between total comfort stage 1 and 2?

Stage 1 have higher nutrients which babies need. While stage 2 has different nutrients that babies need, hence the price is different when older they get. You can do a compare on the nutrients. Do note you can take in stage 1 after 6 months but not earlier with stage 2.

I think it is just that stage 1 is suitable for babies for babies from 0-6 months old, while stage 2 is for babies from 6-12 months old. Other mummies, please correct me if I'm wrong. But I don't seemed to see stage 1 available anymore.
