Is there a chart showing: Brand, Food, Measure Weight and PHE Exchanges for 9 months old? The one I am using is from the doctor, but many baby food is not on it. The list is from 2002. nAlso, I heard there is a book we should buy, what is the name and where do I find it? nMy grandson is 9 months old and I have a hard time to figure these food exchanges out. Help!
