I have a 3.5 year old daughter. When she was <=2 years old we virtually never got questioned about milk, juice, yogurt, etc. Now we get questioned much more often and in some airports they flat out refuse to let us take the stuff. So for a 5 year old, unless they look younger than they are, I suspect you will run into problems. There is a wide degree of variance in treatment depending on the airport. I don't have experience with the airports you listed so I can't comment on them specifically.
