This is what I am giving my 3 year old son, for his eczema:
Daily:
1 Omega Balance 3.6.9.
1 Evening Primrose Oil
1 Cod Liver Oil
1/2 can bristling sardines
1/4 cup canned salmon (with bones & skin)
1/8 cup natural peanut butter (dry roasted)
1/8 cup virgin coconut oil
1 slice bacon (nitrate-free)
1 egg (local pastured)
1 hot dog (organic grass-fed)
In the above list he would be getting at least:
Omega 3: 3340 mg
Omega 6: 1900 mg
Omega 9: 420 mg (maybe more if you count the olive oil the sardines come in)
Total Saturated Fat : 40.75 g (31.8%)
Total Unsaturated: 51.85 g (25%)
Total Fat: 56.8%Cholesterol : .335 g (7.8%)
Protein: 36.6 g (35.4%)
His skin seems to do much better when I include the coconut oil and PB. I'm still tweaking his diet. These figures and percentages above does NOT include the REST of what he eats each day, which may look something like this:
1 c. fresh fruit
1 baked chicken leg
1/2 c. green vegetable with butter
1/4 c. orange or grape juice
1/2 c. coconut water
If the average toddler takes in approximately 1500 calories each day, he needs about six tablespoons of fat per day to obtain 50-55 percent of his calories as fat, which can come from butter, egg yolks, meat fat, coconut oil, whole raw dairy products, olive oil, avocado, nuts and seeds...
Although one's meals should have a relatively relaxed feel and flow from day to day, here are the mathematical details to figure out one's specific fat needs. To calculate the needed tablespoons of fat for an average of 1500 calories, take 1500 calories and multiply it by 0.50 to figure out how many calories are given by 60 percent, which is 750 calories. Then take 750 and divide it by 9, the number of calories in one gram of fat, which gives you 83 grams.
Last step--stick with me here--since a tablespoon of fat weighs approximately 14 grams,39 divide 83 by 14 to get the approximate tablespoons equal to 83 grams of fat, which in this case is just under 6. Therefore, an average toddler needs approximately 6 tablespoons or around 83 grams of fat each day. This same formula can be used with any number of calories to figure out the average number of tablespoons of any size person.

Son's skin is doing GREAT. It has not been red / inflamed for 2 days now. It looks to be healing up. He has been pooping more regularly now (same time every day) and it has been soft instead of hard.
Other notes on his diet I forgot and think are relevant:
We still have him off all Complex Carbohydrates (grains, legumes, starches).
He is drinking kombucha again now. Maybe 3-4 oz. every other day.
We added back raw cow's milk & raw butter to his diet and he seems to do OK with this now.----------------------------------------------------------

Several day's ago we ran out of Omega Balance, so have been giving him only 1 EPO and 1 CLO at every meal. Son's skin is doing BAD. He was up itching all night. Very red & inflammed. It happened suddenly, within a matter of an hour 2 days ago. We were visiting DH's new office. So I wondered if it was something like what they clean with there cause he played all over the carpet... But it hasn't improved since then. Other thoughts: stopping the Omega Balance? adding more milk back into his diet? It's so HARD to keep every variable constant... Inevitably changes in diet/environment happen at the same time whether we try not to.

Sooo... We have an appointment with a new doctor today. First time we've been to one in a long while. I'm praying it goes well. Boy will he have a lot to listen to...

Son is doing much better! After a bad skin week, we finally took him to a chiropractor I had met & he has been adjusting his spine several times now. And all his rashes are healing!
He said something about malabsorption of nutrients & slow digestion being linked to the spine/neurological system & the signals were not getting through. That his own metabolism was very toxic to himself (I didn't totally understand him). He also told me to go easier on any supplements for him (no probiotics), only 1 CLO a day, and his multi-vit.... Possibly it was from birth - cord wrapped around his neck & then suction tube. I think, also maybe from falling off of a changing table when he was several mo. old. I would have never linked those things together. So far, it's helping.
AND this is despite the fact that I added back a bunch of foods to his diet that I had taken out, like wheat, rice, bananas, etc. And he is pooping every day now.

Started giving son a digestive enzyme (Lypo by enzymedica) specifically for fat digestion along with his EFA supplements and meals (and sometimes in between). This cleared up a skin flare-up that had happened. The enzymes seem to help his skin return to normal & his cells retain moisture better.
