I'm like you, blood was the only symptom. My first son had this, too, but
he had terrible reflux and was raging so we ended up on formula. This
time around I saw a pedi GI and gave the diet longer to work out. The
GI was comfortable giving me 8 weeks before re-checking the stool.
Somehow it worked even though I must have eaten something bad shortly
before our appt. I saw small amounts of blood several times after weeks of no blood, and
miraculously 2-3 days after the last sighting, his stool was checked in
THREE different diapers and there was no blood! Stay the course and
give it some more time. You are amazing for limiting your diet to so few things. I'm off dairy, soy, peanut, tree nut, fish, and shellfish and not eating as healthfully as you.
My pediatrician said that after a week stuff should have been cleared out but I respectfully disagree.
