One of the key things in an RCT is that assignment to a group is permanent
for the purpose of statistical analysis of the data.  That means that data
about all babies who were meant to be fed donor milk, will be analyzed in
one group, and the meant-to-be-fed-formula ones will be analyzed in another.
Why can't the babies who did not stay with the assigned treatment be excluded 
from the results entirely?
