You know what, I take flaxseed oil capsules cause the tips of my fingers were splitting heaps (at any one time, I would have about 7 or 8 of them - thumbs included - plastered with bandaids cause they would split and bleed so much!) and I read that flaxseed oil may help that condition. It is a vegetable source of omegas 3, 6 and 9 and the bottle says it may help with blood circulation. The capsules are quite big (if you have ever taken blackmores pregnancy vitamins, they are the same size) BUT you can buy it from health food shops in a cold pressed liquid form. If he eats porridge, you can mix it in and you can't taste it (I tried it with weet bix but you can still taste it). Because it's natural, I can't see the harm in giving it to little kids ... PM me if you want more info! ;)
