Don't listen to the people saying it's too soon to be on stage 1, let alone stage 2. I asked my pedi. at my daughter's 4 month check up and she said I could start stage 1 then...she had already been on rice cereal for a month.
If you're already giving some of the stage 1's and there's no problem, I say give her ALL of them, see how she does, then go from there. Basically, conquer one stage before moving onto another, that's what I did and we had absolutely no problems.
There are a lot of people out there who are hyper-vigilant in regards to allergies and food sensitivities, bottom line is go with you're gut. Some people are a little overzealous, just remember that you have already started your daughter on food....it's not like you're gonna go back now! And you shouldn't either. Roll with it, enjoy it, some kids aren't too keen on eating baby food, especially if you wait until after 6 months to start them on it, so enjoy the fact that your daughter isn't one of those kids!
Bottom line: try ALL the stage 1's before moving to stage 2's. Enjoy beautiful Giavanna!
