Baby eating cheetos at 4 months?

💸Mindy💸
A girl I know was feeding her just barley 4 month old baby Cheetos today. I don't care what she does with her kid, but I'm just curious if babies should be having that at that age? I'm trying to learn things as I go and didn't think babies could have that till about 6 months or later? Not judging her at all, simply curious for learning purposes. 😊
