It is interesting to comment on this subject at this time since we are expecting and six days late.  This is child number six.  Although I, too, am limited on movement due to a previous ceasarean section, I cannot imagine delivering in hard restraints.  It seems inhumane to us.  We support limiting the use of restraints as long as the prisoner does not appear to be a threat to self or others.  Please decide in favor of what is safe for the health of the mother and baby!
