Hello, I need some advice. I bought a thermos funtainer 10oz for my kindergartener. I am having problems with noodles soaking up too much liquid by lunch time. How much liquid do you need? I tried Knorr Alfredo, ramen noodle soup, and macaroni with tomato soup. Each time the noodles were dry or too much liquid was gone so my daughter would not eat her food. Her lunch is 5 hours after leaving home. Thank you
