Portions? In the puree stage

Okay, so I have been researching the main message board and some puree recipes. There are some posts that say eating a cup or even half a cup of food is too much at this stage. Am I eating too much if I have a cup or half a cup of cream soup with non-fat dry milk mixed in? If I make a protein shake with a cup of milk, how much can I drink at one meal? I am getting very confused. I am fearful that I am stretching my pouch if I put too much liquid in it, but some folks have told me I can never have too much water. Does anyone have any sample menus from the puree stage that they would be willing to email me? I have the one page from the MUSC booklet, but I would love to see more than that one example. Thank goodness I have you friends to advise. This can be so confusing!! Hugs, Christine
