Re: What brand rice cereal did you start on?
If you want to start on something I would do oatmeal. Baby oatmeal that is. It's more nutritionally sound than rice cereal.
OR you could make your own with brown rice, which is also better than white rice cereal powder.
I used cereal with my daughter, My son was NOT a fan so we just skipped it and started him on fruits and veggies first.
