I drink fish and papaya soup to boost my breastmilk supply. Apparently it did help me to increase my milk supply as I felt breasts were fuller after taking the soup. I took 3 days continuously during my confinement to see the results. You can find the recipe from here: http://sg.theasianparent.com/fish_and_papaya_confinement_soup_recipe/
My friend used to add a teaspoon of coconut oil to her milo drink (apparently it had to be australian recipe milo for for this to work). She would drink it hot, make a smoothie or make popsicles!
