I have IGT -- left breast is substantially smaller than right (A vs D) and no glandular tissue is developed in bottom quadrants.
With ds 1, we had to supplement from almost the start ( he got jaundice).
With ds 2, we are further along, but he's not gaining weight rapidly. I'm suspecting we may need to supplement a bit to get the weight gain going.
I would love to hear any success stories from anyone who has or knows someone who has IGT. I am feeling positive going into this, but would be buoyed by anything anecdotal.
