Our family includes 6 children from the age of 2 to 18. My oldest 3 girls take the Mediterranean and chase with water. They will take other flavors, as it is a requirement in our house, but the Mediterranean is the one they grumble the least.
The two year old boy (Basil) is the picky one. He is too young to discipline so we either hide the FCLO and Butter Oil in food or when we change his diaper we lube his buns with fclo/bo.
I have seen references from the 1800's that doctors found applying to the skin was just as effective as taking through the digestive track. My observations would concur with the doctors studies from this period.
I will take anyway that is required but if given a choice I like to put the Skate Liver Oil, Butter Oil and FCLO into a small 1-2 ounce glass of warm water or warm tea.... bottoms up.
My wife (Barb) takes it straight up with a chaser.
Hope this helps
ps, Experience from the WAPF conference; I met many young children that ask for seconds. The comfortableness of taking REAL cod liver oil must be cultural or learned. I have found over time one becomes used to taking FCLO without issue.
