YES! the GFCF diet did wonders for our son. Lifted the "fog" so to speak. Took about 3 months of consciously applying the diet but so very worth it.

We did it for 3 months with no changes at all.

After 2 1/2 years of GAPS diet , we do now Gluten Free (and sugar free), and we see a slow but steady progress.

We've been on it for 2 months. I noticed a difference in the first week. Our testing showed sensitivity to casein and gluten.

I have my son has never wanted or took Dairy. But if he wants some of my cereal and it has milk he will start yelling after he eat it, he will start spinning on the floor it is not pretty.
