What is the difference between Stage 1 and stage 2 baby food?

My daughter will be 7 months old in 9 days. She started solids at 5.5 months, she loves all of the stage 1 foods and eats a whole container at a time. I feed her solids 2-3 times a day. She doesn't have any teeth yet. I know the stage 2 are bigger. Is that the only difference? Is it okay to give her those now?... show more My daughter will be 7 months old in 9 days.

And also when can I start giving her finger foods? Like the little puffs and things like that? Do I need to wait till she has teeth?
Thanks!!! =)
