Beverly,
Is the DPT vaccine cultured in eggs?  If so, this could be the dietary insult
causing the bloody stools.  WHy is it that the first thing some docs do is
take the baby off the breast?  Aargh once again!
        It is understanding that neurologic symptoms after DPT are more likely
in infants with underlying neurologic problems.  Could this baby have been
sucking less than optimally all along, leading to a relative lactose overload
(mucousy, green stool & gas)?
Keep us posted.
