For Mobile: MSPI-when would you consider formula? 

DD is still having bloody poops consistently. She had a biopsy done two weeks ago which confirmed allergic collitis. We might go a few days without blood, but then it is back again. It has been 2 months since the blood started, 7 weeks no dairy or soy, 4 weeks no nut or egg, and 2 weeks no beef or citrus.

I have been journalling my foods for the past week, and so far can't seem to find any correlation between the bleeding and what I am eating. I'm being strict with reading labels.

 Any suggestions for next steps I should take? TED? Formula?

She is gaining well and generally seems pretty happy, but the pedi said that since she is still bleeding there may be scarring or other permanent damage happening, and at the last check her hemoglobin was below the low end of normal. I am scared and sad about the possibility of giving up BF-ing, but also don't want to hold on to it if it isn't what is best for DD.

TIA for any advice.
