i do not agree with the saying that rice protein mimics milk protein. the problem with rice is that it is a grain, and grains are EXTREMELY hard for kids under 1-2 years of age to digest. babies lack an enzyme called amalyse to digest grains. i did not give my son any prepackaged snacks like that for a few reasons, one being that a lot of them have ingredients in them that i wasnt too fond of. there are a few alternatives, like these organic corn puffs i give my son. he likes the peanut butter flavor best, and yes i started it around 6 months because we do not have any peanut allergies in the family. that was just a personal choice.
