D.F.
I have done this in the past and it has worked for both of my daughters 2 and 4. I have made some chicken noodle soup and made them drink small amounts of the broth and given them one cracker. I did this at lunch time and at dinner. For breakfast, I gave them fresh juice from and orange and cracker. Not much juice from the orange. Then I let them sleep. It seemed to help them. Something about the broth helped my 2 girls.
