Post Op Diet ????

I am 4 days post op. I am on a liquid diet, I am having little sips of clear broth, tea, posicles, and water. I have protein to make protein shakes, would I be able to add a strawberry or 2, and a slice or two of bannana when I mix the shake in the blender. Before surgery I would usually make my protein shakes like this. In my family we are big protein shake drinkers, even my two little one's love the protein shakes.
