MSPI the second time around

camedowncrushing

DD1 had MSPI, and we didn't figure out until she had blood in her stool.  DD2 is just under three weeks old.  At day 6 she started showing all the colic symptoms so I went dairy and soy free.  It was pretty easy transition for me since I had done it with DD1.  I had my list of all dairy and soy free foods, and so I know i haven't accidentally ingested any hidden dairy.  This weekend she had blood in her stool though.  Has anyone encountered this?  I would have thought we wouldn't have got to this point since my milk is in the process of getting "clean."  It makes me wonder if there is something else I am eating that is also bothering her?  Thanks!
