i have started a baby food business and our products should be in major supermarkets in the next few mths..we actually had some debate in our office about this point, and decided to err on the side of what's best for bubs and label all our single ingredient first foods as 6mths+..at our recent product launch at the pbc expo, we had so many parents saying "oh, so we can't start our bubs on this until 6 mths?What do we do before that?"..our dietitians were devastated at the lack of educated parents in the general community..we will actually have a large advertising campaign coming out later this year about the importance of starting solids at 6 mths will single ingredient 1st foods..i don't think there is enough information out there for parents..
Sorry for my rant..
