Will he drink a bit of juice? Ds is going through a stage too, he basically lives of vegemite bread and cheese (thankfully tho he is still into his fruit too) and I was worried about his vitamin intake so I started mixing a liquid multivit with a bit of applejuice. I don't know of you have heard of "nudie" but they make an apple juice that is only apples and nothing else (sugar and preserve free, only the juice of 20 apples in a carton!) I squirt his vitamin in with that. I wasn't keen on getting him the chewable ones because apparently they are alot like lollies and I didn't want him nagging me for "lollies" all day and having a tanty when I only say one XP
