Our pediatrician recomends against solids for for the first 6 months
for all kids to reduce the likelihood of developing food alergies. (2
years for foods like peanuts and strawberries) The extra bonus was
that the milk stools pass much more easily reducing the problems at
the beginning. Once we started solids the Dr at SB clinic recommended
adding sorbitol containing juices like prune and apple. He also
suggested benefiber. There is also a prescription softener that we
used for a while.

If you are getting bad diaper rash bleeding from the constant stools,
I can suggest using a blow dryer to dry the bottom between changes and
getting a good diaper rash cream. We found a store brand that has 40%
zinc as opposed to the 20% in the well known brands. These two things
helped reduce the rashing a lot, though it didn't permanently clear
until we started a cath scedule. I don't have experience with bleeding
from a prolapse.

As for foods related to latex allergy, there are no studies showing
foods increase the riskof latex allergy. However some people w/ latex
allergy also have reactions to those foods listed.

Congratulation on your baby boy,
Adam
