I bought some yogurt for DS (8 months old) to try. However the only whole fat yogurt I could find was flavored. It's organic and from Stoneyfield so I know it's quality but can an 8 month old have flavored yogurt? I was told it had to be plain and of course not the lowfat or non-fat kind. The flavors I got are banana and vanilla. He's had pieces of banana already.
